Dalia was a great host. She sent me a bunch of suggestions for things to do in Rio while I was there and was very responsive to questions and requests, e.g. being able to check in earlier than planned and checking out slightly later than planned. The studio was small, but comfortable and served its purpose, i.e. a place to sleep. The location was great, only steps away from Copacabana beach and fairly close to the metro also. The energy bill charge was slightly different than usual places, but still didn't really add much to the bill, was just 10 R$ for 4 days of moderate use.
