We had a great experience with Anna's studio in Santa Teresa! Anna was very accommodating (arranging pick up from the airport + letting us leave our luggage at her place all day before a late evening flight). We loved exploring Santa Teresa, and it was easy to get to other parts of Rio: the walk to the Gloria metro station was reasonable (about 15 mins there and 20 mins - uphill - back), there are several bus stops nearby, and we had no problems getting taxis. Anna's studio looks exactly like the photos and felt very cozy and spacious!
