Antonio is a welcoming and helpful host. On the first day he gave me recommandations about the city attractions and tips on transportation, restaurants, ... He's enthusiastic about his city and make sure you have a good time.
The house is very clean and shared with other international travellers. It's actually a kind of hostel.
The location is convenient too as the house is situated 5-10 min walking from Trindade subway station (bringing you to airport) and 15-20 min walking from the city center. I definitely recommend Antonio's accommodation!
