If you are looking for a stay in Rio, I highly recommend this apartment. It is located in a lively yet not-so-touristic area with restaurants, cafes, and bars at night. It is easy to get around to other parts of the city. It is right next door to Jardim Botanico - always a nice walk, and you also have a great view of Crist the Redeemer.
The apartment manager was very accommodating to our needs and times of traveling and friendly in communication.
