I rented Ana's apartment for about 4 months. I really enjoyed my stay there!
The apartment is in a great location, very close to most of the things you need either for leisure or your daily life. The neighbourhood is safe and has good transportation.
The apartment is of a good size, charming, quiet and functional. Some of the decorations are by Ana, which I found lovely. My only two remarks would be that the apartment can be a bit dark, but this also means it is relatively fresh (and I imagine you will spend most of your time outside anyway) and that I had to clean the kitchen, especially the oven, quite deeply before feeling comfortable in using it.
Ana has been flexible in accepting making some additional space for my stuff, which was great, and also with check-in and check-out. She gave me excellent tips on Rio.
I would recommend staying there.
