This is an excellent Airbnb.
The location is ideal, near both Ipanema and Copacabana, and also super close to supermarkets and a metro stop. We also felt very safe, there are porters on the building entrance 24h.
The room itself was exactly as advertised with some very nice additional touches such as beach towels and carrier bags. It was very quiet in the evening and we felt very comfortable there.
Particular highlights: very comfy bed, lovely hammock, excellent WiFi (had to do a Skype interview whilst there and it worked great), lots of tv channels (including in English) if you want a chill night in.
Overall we loved our stay and would definitely recommend this place to any couple wanting to explore Rio!
