It was a great find staying in Debora's flat. It was located really perfectly directly between Copacabana and lovely Ipanema. It's just a 5 minute walk to each beach area, a very nice café is around the corner (my tip: Apetite, 200 meters away, we've been there a few times). It was a very safe stay, and I never felt unsafe at any time in the whole week in Rio anywhere. Checkin and communication was great and really easy. We received several tips for our stay and Debora was always reachable via Airbnb and Whatsapp.
The flat was spacious, the living room area had a ceiling vent, there was a large modern flat TV with internet channels (not really used), and both sleeping areas could be air conditioned (loud during the night as always, prep if you want to sleep with it). Large refrigerator. One large bathroom and a second small one, so if you're a larger group it's perfect (both with toilets and showers).
We really didn't miss anything. The only thing to complain on a very high level is that it's a bit dark. But you're out exploring Rio anyways most of the time. Also the Wifi was working well but was quite slow but sufficient.
Thank you for the great stay in Rio and see you again when getting back! :)
