Portland-based Stoa Lodging has acquired the 96-room property at 521 Sixth Avenue and plans to transform it into Stellen San Diego Gaslamp, a 100-room boutique hotel expected to debut by March 2027. The project will renovate every guestroom, substantially remake the building's exterior and lobby, introduce the property's first food-and-beverage operation and plug the previously independent hotel into Marriott's rapidly expanding loyalty and distribution network.
The makeover is notable on its own, but the economics behind the deal tell an arguably more interesting story. Stoa reportedly paid $25.2 million for Hotel Z earlier this year, substantially less than the property commanded when it last changed hands more than a decade ago. Contemporary real-estate reporting shows Columbia West Properties purchased the newly converted Hotel Z for $34.5 million in July 2015, or approximately $359,000 per room.
That means the Gaslamp property sold in 2026 for roughly $9.3 million less in nominal dollars than its 2015 price, a decline of about 27 percent before even accounting for more than a decade of inflation. Stoa is nevertheless betting that several million dollars in improvements, four additional guestrooms and the considerable reach of Marriott Bonvoy can unlock a substantially different future for the aging property.
Stoa describes itself as a privately held family investment office led by Taylor Jacobs and focused primarily on lodging and hospitality. Its own portfolio identifies Hotel Z as a "value add" acquisition in the heart of San Diego's major demand generators, alongside a Washington waterfront lodging property called The Glen.
Hotel Z's current incarnation dates to 2015, but the building's history as lodging stretches further back. Before pineapples arrived, the four-story property operated as the Baltic, a single-room-occupancy residential hotel containing an extraordinary 221 small units.
J Street Hospitality undertook an extensive adaptive-reuse project that gutted and converted those 221 units into just 96 hotel rooms. The redevelopment replaced the building's mechanical, electrical and plumbing systems and reconstructed its rooms, corridors and public spaces before Hotel Z opened in 2015.
Columbia West acquired the finished hotel that same year and sister company Pineapple Hospitality operated it under the Staypineapple umbrella. The company leaned heavily into its irreverent pineapple identity, something that made the relatively small Sixth Avenue hotel conspicuous among downtown's much larger convention-oriented properties.
More than a decade later, much of that personality is about to be stripped away. The building's blue, gray and yellow exterior is expected to become off-white, with metal louvers and landscaping added to the façade. Taller storefront-style windows will open the lobby toward Sixth Avenue, while San Diego architecture firm Delawie is designing interiors around warmer natural materials, botanical elements and a more residential aesthetic.
Every guestroom will receive new furniture, artwork and laminate wood floors replacing carpeting, along with accent-wall treatments designed to resemble natural plaster. Stoa also plans to source artwork locally.
Curiously, the renovation will actually make the hotel slightly denser. Rather than adding another floor or expanding the building, ownership plans to take eight of Hotel Z's largest existing guestrooms and divide them, producing four additional rooms and bringing the property from 96 to 100 keys. The move effectively squeezes additional revenue-producing inventory from the existing footprint at a property where the building itself once accommodated more than twice as many residential units. Hotel Z is expected to remain open while all of this occurs.
The other significant addition will happen downstairs. Hotel Z currently has no restaurant or bar, but a portion of its lobby will become a café serving coffee and lighter food during the day before transitioning to cocktails in the evening. Ownership has described the concept as locally driven and says it will be intended for San Diegans as well as hotel guests, although no operator, name or detailed menu has yet been announced.
The biggest change, however, may be less visible from Sixth Avenue. Stellen will become part of Series by Marriott, a collection brand Marriott launched only last year as part of its aggressive push into the midscale and upscale hotel markets. Series allows independently branded properties to retain their individual identities while gaining access to Marriott's reservation infrastructure and, critically, its enormous Bonvoy loyalty ecosystem.
The brand is still remarkably young. Marriott launched Series globally in May 2025, and by the end of that year it had opened 37 properties in India and signed 13 agreements for hotels in the United States and Canada, with just two domestic hotels open by year's end.
San Diego is already part of that rollout. Marriott announced in September 2025 that FOUND San Diego would be among the first group of American hotels converting into Series by Marriott, alongside properties in Miami Beach, Chicago, San Francisco and Santa Monica. Marriott's website now lists FOUND Hotels San Diego Downtown as an operating Series property.
Stellen therefore represents another piece of Marriott's surprisingly fast expansion of its newest collection brand into San Diego. In fact, Marriott has already created a live webpage for the forthcoming Stellen at 521 Sixth Avenue, labeling it "New to Marriott." The listing promotes proximity to Petco Park and the Convention Center, complimentary beach cruisers and day-pass access to FIT East Village's rooftop pool and fitness center. It also indicates there will be no on-site parking and, notably for anyone familiar with Staypineapple's famously dog-friendly branding, lists the future hotel's policy as "Pets Not Allowed."
The property will be managed by Evolution Hospitality, which was already recruiting Hotel Z employees this summer. Recent listings included front-desk positions paying $19 per hour and housekeeping positions advertised around $19 to $20 per hour.
Stoa founder Taylor Jacobs has described the acquisition as a long-term bet on downtown San Diego, citing the property's unusually advantageous position between some of the city's largest visitor generators.
That geography is difficult to miss. Hotel Z sits on Sixth Avenue between Island and Market streets, only blocks from Petco Park and the San Diego Convention Center and within walking distance of the waterfront. It is precisely the kind of location that can draw baseball visitors, convention attendees and leisure tourists without the hotel itself needing the pools, ballrooms and other expensive amenities associated with larger full-service properties.
And despite persistent concerns surrounding downtown San Diego, the broader hotel market has recently demonstrated considerable strength. Industry data for June 2026 showed San Diego County hotel occupancy at 84.4 percent, with an average daily rate of $234.79 and revenue per available room up 12.1 percent year over year. Downtown and Marina hotels commanded the county's highest average daily rate at $291.17.
The investment nevertheless arrives during a complicated period for the Gaslamp Quarter itself. Downtown businesses and civic leaders continue grappling with concerns about homelessness, public safety, vacancies and the district's evolving nightlife identity. Most recently, a series of highly publicized confrontations around Fifth Avenue and F Street prompted San Diego police to launch a high-visibility enforcement effort dubbed "Operation Last Call."
Jacobs told the San Diego Union-Tribune that he remains confident in downtown despite those challenges, pointing to convention traffic and tourism and saying he believes city officials and downtown stakeholders will continue investing in the district.
The purchase price adds another dimension to that optimism. Hotel Z was essentially brand new when it fetched $34.5 million in 2015; Stoa bought the same 96-room property for $25.2 million approximately eleven years later, after a decade without a major renovation. The lower acquisition basis gives the new owner room to invest heavily in repositioning the building, although Stoa has declined to disclose the renovation budget beyond saying it will total several million dollars.
For travelers, the transformation will ultimately be more straightforward: Hotel Z and its relentlessly cheerful pineapple aesthetic are going away.
In their place will be a quieter-looking boutique hotel with four more rooms, a lobby café and cocktail bar, a newly subdued façade and one enormously important corporate connection. Stellen may be marketed as an independent San Diego hotel, but behind it will sit the reservation system and loyalty membership of the world's largest hotel company.
Hotel Z will remain open at 521 Sixth Avenue in San Diego's Gaslamp Quarter during renovation, with Stellen San Diego Gaslamp currently expected to make its full debut by March 2027.
