I had a great time staying with my boyfriend at Axel's place. Axel is a very cool and fun host! He shared with us his experience about Rio and gave us a lot of great tips! Besides, we had the opportunity to do a tour of two different favelas with him, and on another day he brought us to a beautiful, wild and natural beach in Rio from where we watched then an amazing sunset.
I highly recommend to stay at the Casa 48, you will definitely not regret it. Staying in a favela was such an interesting and positive experience. We enjoyed living in an authentic way, close to local people, in the lovely Santa Teresa.
The description and the photos on AirBnB reflect very well how the house is, and the view over Rio is really breath-taking! :)
