I grew up in Rio's Botafogo neighborhood, and this place made me feel right at home! One block away from a lovely bakery, on a quiet lane between two major streets that make navigation very easy. Many great local bars and restaurants within walking distance. The place itself is very well kept, with a good AC unit (which we were very thankful for).
The building is a little old, so be aware that you're not staying at a hotel, you are living the way we cariocas do: somewhere simple, charming and cared for lovingly :)
