Walked in told only had one night reservation. But we booked two nights was told had to pay for next night now or could get two nights. Decided to go somewhere else the next night. Go to check out and being told we had a two night stay and would be charged $100 fee. The guy we checked in with night before told us the wrong thing and seemed shady about how he was trying to get more money out of us. Hotel has apt of homeless people camped around it. Does not match the picture online.
