Diogo is a good guy and answer very quickly. He told me lot of tips to do in Rio de Janeiro and his apartment is in 20-30 metres from metro station General Osorio. That's awesome.
Favelas are close from here but I don't feel uncomfortable and have no surprises about it. During carnival days we don't be bothered by the music and party, so it's a quite silence area, and this is perfect to rest.
Air Conditioning works good. Happy to have it in one of the rooms and the saloon the main one.
I have had a very great time there. :)
The unique bad point is that could be a little bit cleaner.
I recommend it
