We really enjoyed our stay in the apartment. I think the size is just enough for 2 people, maximum 3. I wouldn’t recommend it for 4 people, because it would be so tight.
The apartment was very close to metro station, restaurants, beach.
Communication with host was super easy. They let us to check in early.
The next door apartment (the one with the bike outside) sold us very good lunch for 10RS every day. I recommend it.
If we visit again Copacabana, we would stay in this apartment again
