This AirB&B is really well located. At 5mn from the beach and from the major street where you will find all restaurants and bars. It is safe and enjoyable to walk around.
The wifi works perfectly and I could work without problem. Just one things, the second bed is a sofa bed located in the living room and not really comfortable.
The communication with the owner was really good.
You will enjoy your stay in this AirB&B if you come to Rio.
