We stayed at Anna's place for 4 nights during Carnaval and had a great time. They've made it super easy to check in with a keypad on the front door. The place is really cool and they've done a great job decorating it. I still can't believe we got an awesome private room + bathroom for less than two dorm beds in a hostel! We had to pay extra for A/C which wasn't mentioned until a day before so keep that in mind. It's not a lot extra and it's pretty necessary in Rio. Santa Teresa is a cool neighborhood with lots of great street art. Near the house, there's a supermarket where you can get most essentials. They also keep things like coffee and milk in the house. There are a few restaurants and bars nearby as well. For getting around, there's a bus stop just up the hill that will take you down to Lapa or even all the way to Christ the Redeemer the other way. Uber is a necessity here. It saved us lots of hassle and money and we used it get to/from the airport and to get back late at night. Overall we really enjoyed our stay and hope to come back outside of Carnaval to see more that the city has to offer.
