While the outside and lobby looked pretty nice, the room had a "cheap" feel to them, especially given the rate. The couch was a little gross, and the rail for the bathroom door was held in place with a crude shim that protruded from the rail. Will look elsewhere on my next trip.

A fire alarm went off so the building had to be evacuated. Only one of the fire exits (staircases) was open for all of the floors to file out. The other exit was blocked off. No one from the property appeared to be assisting in the evacuation.

Good place to stay, but if you don’t wanna be bothered, don’t stay here I had my do not disturb sign on for the three days I was there and housekeeping would still come knocking multiple times within an hour even after telling the front desk to have housekeeping stop knocking, they would still come do it

Ice Cold

I reserved 2 rooms, one of them was for my mother. Her room was ice cold. Could not adjust temperature. Called desk around 12am to have them check thermostat and they said it was broken and had to order a part. They offered to move my Mom who is 86 years old, and unpacked her belongings, did not was to move. The room was so cold that she took the comforter off the other bed to get warm because she put to the covers over her head for warmth. Very uncomfortable!
