The hotel has aged and not well maintained over the years. The window to our bathroom was broken with a section broken out. Unfortunately, you cannot regulate the temperature in the room. We loved the art deco appearance in the online photos and in reality it was not thoughtfully maintained. Staff were amazing, helpful, and kind. Another guest, above us, stomped on their floor and knocked on the walls until the early hours. We felt safe, but sad about the state of the property.
