I dealt with Sandra who was very accommodating and a good host. She had good recommendations for our stay in Rio.
The apartment had all the basics that we needed, and was clean. The facilities in the building (gym and pool) were a good addition to our stay.
The location was only a short walk to the beach in what felt like a safe neighbourhood. It is a little bit further away from the main part of Copacabana, but still relatively close and only a cheap Uber fare away. It's also close to a subway station which was handy for when we did our sightseeing.
All in all a great place to stay with friendly hosts.
