My experience with Leandra and her house can be considered positive. She's very helpful, kind and serves a nice breakfast included in the price. The room she gave me was a bit narrow and the bed was too hard for my personal opinion.
The position of the house is not in the centre, but easily reachable by metro and bus, and good for keep fit as well, since from the bus stop you have a 5 minutes walk but with an important pendence.
From her house you can reach a very nice sector of the huge national park of Rio "Tijuca", it's only 10-15 minutes by bus, and i definitely recommend you a visit.
