One of downtown Seattle's better known Marriott spots is in for a serious makeover. The SpringHill Suites at 1800 Yale Avenue is slated for a renovation and partial rebrand that would create a dual‑branded SpringHill/TownePlace by Marriott. The plan calls for several guest floors to be converted into extended‑stay units under the TownePlace Suites flag, while the rest of the building remains SpringHill Suites, nudging the property more toward long‑stay visitors in the Denny Triangle and South Lake Union area.
According to CoStar, Legacy Development & Management intends to turn multiple levels of the 10‑story hotel into TownePlace Suites extended‑stay rooms and operate the address as a dual‑branded Marriott property. CoStar's report notes that a developer rendering shows distinct extended‑stay floors paired with shared public spaces.
Per Moody National REIT II's SEC filing, the REIT's subsidiaries entered a purchase and sale agreement with Legacy DTS LLC on Sept. 15, 2025, to sell the SpringHill Suites at 1800 Yale for $51,000,000, with closing scheduled on or before Dec. 2, 2025. The 8‑K identifies Legacy DTS LLC as the buyer and records the agreed purchase price.
The 10‑story, 234‑room property sits at the southeast corner of Stewart Street and Yale Avenue, according to Hotel Business, and appears on Marriott's site as SpringHill Suites Seattle Downtown/South Lake Union at 1800 Yale Ave. For years it has catered to convention traffic and tech travelers working the South Lake Union and Denny Triangle corridor.
What The Owner Is Proposing
Legacy's concept splits the building into two experiences: dedicated extended‑stay inventory under the TownePlace Suites banner and more traditional SpringHill Suites rooms elsewhere in the hotel. So far, public reporting describes the project only in broad strokes. There is no published construction schedule, financing breakdown or detailed scope of work that spells out exactly how the conversion would unfold.
Why Dual‑Branding Matters
Developers and hotel operators have been leaning into dual‑brand setups that let them court quick business trips and weekenders alongside longer‑term guests without adding another building. Hotel Dive reports that configurations with shared lobbies and clearly separated room blocks can, in some cases, lift both average daily rates and revenue per available room for owners.
Local Impact And Next Steps
If this conversion moves ahead, the extra extended‑stay rooms could give contractors, relocated tech workers and other long‑term visitors another option close to major employment hubs. King County's 2025 assessment report indicates that hotel performance in the region has been on the mend since the pandemic, while at the same time being reshaped by changing corporate travel patterns, a combination that has owners looking for more diversified revenue streams.
For now, there is no firm construction timeline or publicly available permit set, and it is not yet clear whether hotel management will change along with the branding. More specifics are likely to surface in city permit records or future filings from the parties involved as the plan moves through the pipeline.
