The apartment is very clean and nice in a modern building with a very nice indoor and outdoor community area. We especially liked the shower. As almost everywhere in Rio, it is relatively noisy in the apartment due to the thin windows. But it has been like this in every apartment in Brasil for us, so it’s probably like this everywhere.
The apartment is directly at the metro station, so you can get anywhere. If you want to go shopping, to cafés and the beach, you can take a 20 minute metro to Ipanema and Copacabana, it is the easiest and most comfortable mean of travel and really safe. If you are there every day, maybe looking for a closer option might be a good idea though, to avoid the daily metro ride.
