Booked a triple room during Carnaval. Plenty of space, comfortable beds, very quiet, daily room servicing with fresh towels, bar fridge, good air conditioning, extensive buffet breakfast any time you liked between 6:30am and 10:30am, friendly staff (mostly Portuguese speaking only). Supermarket across the road for any snacks you might want. Opportunities for improvement? Only small things: WiFi only worked at one end of the room, waste bin for the toilet was too small for three people, shower floor was too flat so soaked the bath mat during each shower.
Surrounding area is not that nice compared to the south zone of Rio, but is a lot better than the downtown Centro area. We felt safe enough to walk to and from the Sambadrome.
Would we go back? Yes, in a heartbeat.
