The airbnb is located in a former favela, but it seemed very safe, most of the time there are policecars driving through the neighbourhood, we walked home also at night and it seems as living in a village. We had only good experiences!
You can reach the beach within 15minutes walking, or you take a cheap mototaxi (around 3real) which would take you 3 minutes.
The airbnb look as of the pictures, we also had our own bathroom which we didnt expected.
The hostfamily was very friendly! I would definitely recommend to stay at this place!
