Room had dirty bathroom (someone's else's hair on floor). Second room's bathroom was no better and was marginally cleaner. Would not go again.
This is most surprisisng as Brazilians are very clean and pride themselves on their excellent hygiene.

1- Bathroom sliding doors in the room do not provide sufficient privacy to your companion - very, very! inconvenient!
2- Noise from room aisle was quite disturbing during the night - I couldn´t have a steady sleep;
3- Mosquitoes everywhere: at the japanese restaurant, at the dancing lounge and reception lounge - probably do to a awful smelling river nearby.
