Katia is a wonderful host. All the communications we had with her were timely, courteous and helpful. She even greeted us at check in and showed us around the property. She spent time giving us tips about getting around/being safe in Rio.
The property was as advertised(except bathroom was a little smaller than expected) sparkling clean, every amenity you could need was provided(umbrella, first aid kit, universal plug adapters etc) She even provided snacks and drinks in the fridge!
The only hiccup we had was resolved quickly(the electric shower is too powerful for the buildings power grid, so don't expect more than a warm shower).
Location was great, in the heart of Copacabana. Lots of grocery stores, restaurants, retailers, metro station and the beach within two blocks.
The WiFi modem, while working fine, had a slow internet connection, so be prepared to wait for long downloads/uploads/streaming times.
We would definitely recommend staying here, just be aware plus sized people might have trouble maneuvering in the bathroom.
That being said, Katia's hospitality is truly something you should experience for yourself
