This is a great place to stay if you want to enjoy Rio de Janeiro. The apartment is clean and cozy. Carlos is a great host. He is very communicative, friendly and he knows his way around the area. He gave me some very good recommendations for places to have breakfast and lunch.
As for the location, as soon as you walk out of the building, if you are feeling like going to Copacabana, turn left, if you want to go to Ipanema, turn right. You won't have to walk 10 minutes in either direction.
I loved every minute of my stay here. I highly recommend this Airbnb.
