While digging into the preparations of the Book Tower coming on line and the conversion of several floors into a hotel in the Book Tower thread, I came across this description in Crain's of Gilberts growing role as a hotel owner.

The fourth through eighth floors of the Book Tower on Washington Boulevard downtown are in the process of being turned into 118 Roost Apartment Hotel studio, one- and two-bedroom units that will be managed by Philadelphia-based Method Co., Dan Gilbert's Detroit-based Bedrock LLC real estate development, management and leasing company said Tuesday morning.

Roost also becomes part of Gilbert's growing portfolio of downtown hotel properties, joining the Shinola Hotel on Woodward Avenue and the Courtyard by Marriott property on Jefferson Avenue, plus a series of other buildings and developments that are targeted for hotel use in the future, including the former site of the J.L. Hudson's department store and the former Detroit Police Department headquarters on Beaubien Street.
