I stayed in the apartment for four nights during the carnival in Rio. The location is superb, very near Beaches and easily accessible with public transportation. Can highly recommend the place.
Vinícius is very kind and responded quickly to all my messages and was helpful.
There were some ants in the kitchen, but they kind of disappeared after the first day. Also, the bathroom door is a foldable door, that does not really close. So if you stay there together, ideally you should be good friends or family. All in all, I have a fabulous stay.
