The apartment is great located. Close to Ipanema beach and Copacabana beach. The metro is right in front of the building and buses to all around the city run a couple blocks away.
The apartament is perfect sized for vacations with storage space to leave everything you had on your suitcase .
We ended up sleeping on the couch to avoid going up and down the stairs since the cealing was kinda low, and the couch bed was really comfortable so for us it worked just fine.
João was a great host, really thoughtful . we had some issues with our flight and he waited for us a couple hours later with a great smile.
I recommed the place to have a beautiful stay in Río like we did :)
