The room we got on arrival was aged and had a clogged drain in the shower. View was nice, but the furniture had issues (many visible impacts from use, water damage at the floor level). Since the shower drain was clogged, the notel staff offered to move us to another room (we were staying 7 days). They offered one room on the 6th floor with partial view only, and another option on the first floor. Because the hotel is right on top of a large road ramp with a homeless person that chooses to holler at cars every couple minutes, we thought we would be too close to the source of the noise and declined the first floor options. We later realized first floor rooms at a perfect view on the fountain where more homeless people bath when the weather is hot, and we felt comforted to have avoided this view.
The second room also had issues with water damage, but less visible impacts on furniture. The shower drain was not clogged, but the floor of the shower was inclined in the wrong direction, away from the drain, resulting in water not draining fully after any shower.
The second room also had issues with the air conditioner, which was untrollable, no matter the temperature we selected on the remote. The room always ended up so cold we had to turn off the AC in order not to freeze (a problem during the night in Rio when the weather outside is quite hot).
Overall, this five star hotel does not meet the standards I have experienced when visiting five star accomodations across US,Asia&Eur.
