In general, our stay was ok....
The apartment is quite big for 4 people, the main bathroom is clean and the shower, even thought didn't have hot water all the time, was good most of the time. The rooms are great, and the air con is def one of the best things in the house. If you wanna chill, the living room is definately not the place for it, the couch is quite uncomfortable, it only fits 2 people. The suburb is very calm and safe, not much to do around that area tho, get a cab and go to the hot spots close to the apartment (around 20 min away, ruffly...)
Althought is quite far from everything, is a good place to stay in Rio.
Now, when it comes to the host, I'm not sure if I would recommend her...Not a very easy going host...
After all, yes, we had a good stay in Rio, and I sorta recommend the place...
I hope this help!
