We loved our stay at Raul and Flavio's place. They were very welcoming and helping. They left some fresh fruits, and beers, which was pretty cool.
The apartment is great, in a safe area. It is big, well decorated. We really enjoyed the outdoor areas, especially the one with the dining table and a nice view at night.
Some cool restaurants of Santa Teresa were 15 minutes away on foot but it was not easy to walk because of construction work.
The only inconvenient is that the area is a little isolated in Santa Teresa. But the apartment is great so it didn't really matter at the end.
