I stayed 6 months at Yuri's apartment in Copacabana. I felt comfortable renting from him because I stayed at his other apartments during some of my other shorter visits to Rio. The apartment is fully renovated and has everything that you need for a comfortable stay. It is located 5 minutes walking distance to the nearest metro station and only 2 blocks away from Copacabana beach. The wifi was reliable and fast, the porteiros at the building entrance were always nice, and there are so many restaurants and groceries stores within walking distance from the apartment. I didn't have many issues during my stay here, but if I did, Yuri was quick to reply and quick to fix the problem.
