The location is top notch. It is super close to Copacabana beach, thousand of shops and restaurants, bus stop and metro station. It is also very safe as the building has 24/7 security personnel.
The single room itself is small but compact. It has everything listed. It is sufficient for me during my stay as I don't spend much my time in the room. The Wifi inside the room is rather patchy though.
Gizela is super helpful. She helped me with information on where to eat, how to go around Rio by public transport, etc. She allowed me to check out later than what listed which is very nice of her.
