This was one of the best experiences I've had overall in my many years using AirBNB, both in Rio and elsewhere.
Cristiane is extremely kind, very helpful, and prompt and clear in communication. I couldn't possibly have asked for a better host.
The place itself is immaculate, the building is quiet, and everything you need for a short or longer stay is in the apartment. It's located literally about a 3 minute walk from the beach. Out the door and the next block, and it's right there. Plenty of places to eat, drink, and have fun. Metro is relatively close as well.
I wouldn't hesitate to recommend this place to anyone thinking about getting an apartment in Copa. I'm very grateful to Cristiane, and her friends who helped check me in and out.
