The staff were courteous. The facilities were dated, room cleanliness was average, and the bed mattress seemed like it should have been replaced by now. Providing room service every other day reminded me of COVID days. It would be nice to get daily room service. Television was cumbersome and lacked many channels. Most importantly, the shower's hot water was hit or miss. Very frustrating when one is trying to get to work! About what I would expect for the price.
