A small apartment in the middle of Copacabana close to the beach. Right opposite is a bar with fresh fruit and fruit juices every day - a great spot to buy breakfast. The immediate neighborhood has many bars and restaurant and even a third wave coffee shop around the corner (Cafe Ao Leu), which is rare in Brazil.
We felt save to walk around until 10pm just don’t show your phone and don’t take a bag just in case. But that is normal for Rio.
The communication with the host was the easiest! And very friendly.
Two things you might consider with this apartment is that it is quite loud at night due to a live music bar right opposite. So maybe bring earplugs if that would bother you. And the equipment of the kitchen is not extensive - but the basics are there.
All in all, we were satisfied with our stay in Rio. If you are there don’t miss the sugarloaf mountain if the weather allows. That was the highlight of the city for us.
