I stayed at Guilherme's for about 10 days and it was a good experience. The room I was given was not the one advertised on the website but it was good anyway and I didn't have problems with that. The house was clean and the location very convenient for enjoying the beach, for going out, for food shopping and for moving around the city (metro station and buses lines are just down the street). I always felt safe and overall enjoyed my time there. Guilherme was very friendly and available for anything I needed, from solving little problems at his flat to giving tips about where to go and what to do in Rio.
