AC Hotel Detroit is now open in the Bonstelle neighborhood of Detroit. The 154-room, 10-story hotel, jointly developed by Peachtree Group and Roxbury Group, is the first AC Hotel in southeast Michigan and the third in the state. The AC Hotel Detroit at the Bonstelle will be Roxbury’s third hospitality project in Detroit, Roxbury said in a statement. The hotel is near Little Caesars Arena, Orchestra Hall, Wayne State University’s Mike Ilitch School of Business and the Detroit Medical Center. It will feature a rooftop venue and restore the historic Bonstelle Playhouse, located on Woodward Avenue, to its original 1903 Albert Kahn-designed exterior and 1925 interior redesign by theater architect C. Howard Crane, both slated to open this spring. Stonehill, a Peachtree Group company, funded the project along with Flagstar Bank, Bank of Ann Arbor and Invest Detroit, the statement said.
