I spent 3 weeks in Patrick's house and was very happy with the whole stay.
The house is very spacious and nicely decorated as on the pictures, thoroughly cleaned up once a week. It as well has hammock for lazy days :).
There is Baixo Gávea meeting point nearby where a lot of cool people are gathering in the evenings. Buses and taxis are right around the corner which opens very quick and convenient access to beaches and city center or other destinations.
Patrick was very helpful and always available, as well very welcoming and I had some very interesting conversations with him.
Overall I couldn't have picked a better place to stay for my vacation, I enjoyed it a lot.
