My boyfriend and I stayed at the Rio for three nights and decided we will never return. First off i noticed several long hairs on our bed, so I pulled back the covers to check the sheets where I found even more smaller hairs in the bed...nasty! We called housekeeping and someone came up to remake the bed. We then found that the safe in our room didn't work, our shower was broken, and the door to the hotel room had issues closing properly. The repair man told us that some of the doors have closing issues due to their age and he couldn't fix the problem. After having the safe and shower repaired we were given a $40 credit toward food in the hotel. FYI - the Rio Carnival Buffet is not worth eating at even when it's free!
Do see Penn and Teller, but don't say at this hotel!!!!
