The property needs to be remodeled as it's completely outdated! The door on the microwave in my room was broken. When we reported it, we were advised there was no maintenance staff on duty. We weren't even offered a room change, and the hotel was not full! An entry door which needed key card access for entry after business hours was not secured.

The check-in was smooth. They place a $50 per day hold on your credit/debit card for incidentals which you get back after check-out. The room was immaculate. I loved that the living room was separate from the bedroom. The bathroom is really small but other than that the room was great! There's a skywalk that connects to the Horseshoe Casino. That was great because I could easily access the restaurants and bars at the casino. The hotel does have a parking lot in front of it that's free and there's free parking at the garage that's connected to the casino. Overall the hotel was good; however, one set of elevators weren't working which caused an inconvenience and I wasn't able to connect to the Wifi.
