Hilton Garden Inn Cincinnati Downtown

Downtown Cincinnati's former Procter & Gamble office tower at 299 E. Sixth St. is being converted into a 130-room Hilton Garden Inn, a $31.8 million project backed by Ohio historic tax credits. It's a mainstream select-service brand rather than the boutique conversions reshaping the rest of downtown, targeted to open by the end of 2026.

The place

299 E. Sixth St., in the heart of downtown Cincinnati's business district, a block from Fountain Square — a location dense with office-to-hotel conversions but until now without a Hilton Garden Inn of its own.

The concept

The project converts the Duttenhofer Building, also known as the Sycamore Building, a former Procter & Gamble office tower that had sat vacant and unsuccessfully marketed for sale for years. Cincinnati-based Keystone Hotel Group (principal Subhas Patel) and Sun Cos. are behind the $31.8 million conversion, which was awarded $3.15 million in Ohio historic tax credits in June 2025; Stonehenge Building Group is the general contractor. It is a first-time hotel conversion of the building, not a rebrand of an existing property, and will operate as a standard Hilton Garden Inn rather than one of Hilton's boutique or lifestyle brands — a business/select-service play on downtown's office-conversion wave rather than a design statement.

Dining & wellness

Plans call for a ground-floor restaurant and meeting-room space as part of the conversion, but no operator, chef, or amenity details (pool, bar, spa) have been announced.
