Marcia and Luiz are very friendly and warm hearted hosts. I was picked up at the airport and my hosts always helped me if i had problems. I stayed there for an exchange semester. It is 15min to FGV university by taking the stairs down to Botafogo. The neighborhood is quiet and safe and a bit apart from the city center. The room is in a house which is shared with the hosts, dogs and maybe other airbnb guests. In the time i stayed there, other rooms were also rented to other students, which was nice to get to know other people. If you want to move in with a friend it is possible that another room is available.
Thank you Marcia and Luiz for hosting me. I had a good time at your place!
