We stayed 10 days at Tons' and enjoyed every single day. Ton is warm, helpful and amazing host, he helped us with any question we had, took us to buy a SIM card and was not tired to give us advice on sights in each part of the city plus locations only locals know about. The room is carefully decorated with cute plants and is very comfortable. Located in Botafogo, very central close to the subway, that takes you in no time either north or south to all points of interests.
We had a great time in Rio and would definitely recommend/come back to this place any time!
