Hard to beat for the price. The rooms are small, as are the hall baths, but comfortable and clean. Quieter than I expected. Would definitely return.

The room had everything we needed. We stayed during the Superbowl and had no issues running into other guests when we needed the shared shower or bathroom. It was cleaned and well maintained and we were very happy with our stay. The weather was great, so no AC was not an issue for us. The ceiling fan and window was all we needed. But if it was hotter outside, we may have struggled without it. Great customer service and great location. We dont ask for a lot when we travel and are happy with all the basics. But if you prefer a four seasons, then obviously look elswhere!

I’ve stayed at this hotel at least 20 times over the past few years. The room quality hasn’t changed much and needs an upgrade . However my stay this time was one of the worst I’ve experienced and most likely will.be the last time I stay. There . The room was on the second floor and around 1 1AM delivery trucks began to show up and the entire night it was loud as a stadium out front and I don’t know who is more at fault . They should comp me a room for getting maybe an hour of sleep the entire night . We shall see
