We spent three nights at Antonio and his mother's apartment. It's very conveniently located; though there are few tourist attractions in the immediate neighborhood, being close to the subway means getting both to the center and to copacabana/ipanema is quick and easy. The building and the apartment are very nice. There are lots of people around, since there are several rooms being rented out. Antonio is very friendly, talkative and helpful, even inviting us to dinner on the first night. Recommended as a place to stay!
