Our stay with Celia in Rio de Janeiro was excellent: we were located in Ipanema, so we could walk everywhere around (or simply take a bus) to the main touristic locations, which Celia recommended.
The room was very clean, and Celia provided a great breakfast every morning, including various types of Brazilian fruits. In the afternoon, due to the weather, the room was very hot, but the air conditioner and ventilator in the room worked very well, so it was not a problem (and most of the time we were in the beach anyways). I highly recommend the place for anyone looking for a great stay in Rio!
