Sunstone rebranded it as Hyatt Centric under a franchise agreement that expires in 2039, according to Sunstone regulatory filings. Sunstone is marketing its only other hotels in Chicago for sale, the Embassy Suites by Hilton Chicago Downtown at 600 N. State St. and the Hilton Garden Inn Chicago Downtown/Magnificent Mile at 10 E. Grand Ave. The properties, which formally went up for sale last fall, have 725 rooms between them and were expected to fetch combined bids of close to $130 million, according to industry experts.
