Mario's place is nice, in a good location near the beach and I was very happy with the apartment. Though I didn't meet Mario, he emailed me before my stay and gave me very good information including how to catch bus from the airport to his apartment. Once I arrived, he had a helpful book with good information about tours things to do and good places to eat. Very cozy place with A/C and everything you need! The next time I'm in Rio will definitely stay at his place again!
