Th apartment looks exactly like in the pictures. As previous hosts said, it's small but convenient and nicely decorated. It's definitively suited for a couple. The bathroom is particularly tiny and not suited for too overweighted persons (we are not but i wonder how my brother would have entered the shower, really).
Location is just perfect ! Ipanema is a great neighbourhood for a touristic stay. We felt great and secure. This was key to enjoy Rio as we did (we really did :-))) ).
We have had no single issue with the apartment during our stay. Everything was functioning properly.
Communication with Ana was easy and always extremely responsive.
The only "negative" comment i could make is that the cleaning was not perfect when we entered the apartment (some hair on the sheets and many in the bathroom). But it seemed that there had been no water for a couple of hours just between check out of previous hosts and our arrival. It might explain it. To be honest, it was not such a big deal to us as the apartment is small and we could finish the cleaning within a couple of minutes.
Overall a very good and pleasant stay, and I would recommend Ana's apartment without any doubt for a couple who wants to discover Rio.
