8/10 Very Good! (9,797 reviews)

Room was clean. Only interaction i had with staff is when i checked in and checked out. You should add on your advertisement, parking that you pay 62 a day for has no in and out privileges. No one rents a car to leave parked. How many times a day do i have to keep paying 62? I gave it a food rating ...
