I didn't have the chance to meet Rodrigo, but Pauline was such a lovely host. It was my first time in Rio and Pauline gave me a quick map tour over a nice breakfast and coffee as soon as I arrived. The Rio guide she lent me was essential for the 4 days exploration.
The house is lovely, very private and has a fantastic view from the top of the hill. It is indeed 10 minutes walk from any of the metro stations Catete and Gloria, so it makes it easy to reach any place in Rio. It's on a quite steep hill, so the walk will surely keep you fit, but the view and the quietness of the place are surely worth it!
I had a perfect break and I would return to Pauline and Rodrigo next time I visit Rio.
