As I had never been to Rio, I was a bit worried while searching for a place to stay. Thankfully, Ipanema is a great place to stay, and Claudia is an attentive host.
The apartment is in the ground floor, right beyond the garage gates of the building. During my stay there it was clean, quiet, and I felt safe, as the apartment, while on the ground floor, is inside the building grounds with a heavy gate. It was the perfect place for me, but I spent almost all my stay in Rio working, not in the apartment. If you are planning on spending a lot of time inside the apartment it might be a bit hard that there is not very much natural lighting; the only window is in the bedroom, and that one being in the ground floor means you don't have much privacy if you have it open. That's really the only "bad" thing I can say about the place, and it probably won't affect most people (Ipanema is lovely. Don't spend your daytime inside!). It didn't bother me.
Thank you, Claudia, for the hospitality!
