Great staff, shout out to Bianka for starting our stay with such a warm welcome. Clean, spacious room and lobby. Level III served excellent food - great staff there as well. Loved the location of the hotel. There are overnight parking garages right across the street for $40/night. Would stay here again.

Stayed with family · For friends and family

Excellent location and very clean. Pristine rooms with a spacious bathroom.. The bed was also very comfortable however, for a hotel in this category, we felt it lacked some amenities and atmosphere .there wasn’t much happening in the hotel and many things seemed to close quite early. Our room was supposed to have a city view, but it almost faced another apartment building. We also tried the Hotel breakfast one morning and found it quite pricey. Overall comfortable stay in great location, but it didn’t fully meet expectations for this level of Hotel.
