Marriott website showing its available for booking. Cat 6 property. When someone stays there, please do a trip report in this thread. Also, if you can post what the brekkie situation is I'll update the exec lounge sticky. Given it has an indoor dog park it's obviously pet-friendly.

From Marriott press release:

Metropolitan at the 9 Cleveland - Ohio
The former AmeriTrust tower and historic Cleveland Trust Rotunda have been transformed into The 9’s complex, which now houses the new Metropolitan Hotel and concierge living apartments for local residents. The Metropolitan Hotel is located inside The 9 and features 156 boldly designed rooms and suites. Adega, the hotel’s restaurant features a 15-foot wine vault, chef’s table and the largest outdoor dining patio in the city. During the week, The 9’s historic bank vaults are used as unique meeting rooms. Located in the basement of the rotunda, there are four historic bank vaults. Inside the extremely large, circular steel-and-glass doors, there are safety deposit rooms that formally belonged to famous Clevelanders. The historic underground vault space has been transformed into the probation-era cocktail bar, Vault, where locals and guests can enjoy a one-of-a-kind cocktail experience. Completely separated from Vault, there is an exclusive speakeasy where travelers can visit by exclusive invitation only. Guests looking for a drink with a view can visit Azure, 150 feet above the street and the largest rooftop bar and sundeck in the city.

From hotel website:

This iconic hotel features 156 beautifully designed hotel rooms that engage your entire experience absorbed in the excitement of downtown Cleveland.
