Maria is a great host who was very willing to help us out during our stay.
The apartment is very centrally located making it a quick Uber ride to most popular destinations. However, you have to walk at least 15-20 minutes to get anywhere by foot.
The apartment itself is beautiful and great for a short stay. However I would advise against an extended trip for more than 1 or 2 people since the kitchen is not very well equipped and there is not much comfortable seating in the living room.
Especially for the price, this is a good place to stay in Rio de Janeiro.
