Definitely didn't end up staying and had to lose money because they wouldn't refund us. It was not a safe place for children. The parking garage is like a block away in the sketchy part of Down town. I couldn't imagine staying so we didn't. I wouldn't have been able to sleep because it was scary ...

Smooth check-in, comfortable clean bed, easy checkout. There were a few elevators down and the hotel was possibly completely booked - very long wait in the morning to get an elevator down so we took the stairs from 10th floor.
