I enjoyed my stay for two weeks in Rio at Mario's apartment. I stayed in the larger bedroom, which is very private. The king bed was very comfortable, the room and connected bathroom were clean, and the noise level was low, so there were no problems with sleeping. The security in the building is very good, and the location is excellent, with Copacabana Beach only one short block away, and banks, grocery stores, a post office, many shops and other services within 2-3 blocks. Mario is a friendly guy who is very knowledgeable about what to see and do in Rio. In all, it was a positive experience, and if I return to Rio, I would certainly stay there again.
