We had a great time in Rio. The location is safe and very nice, really close to the metro which makes it easy to reach almost every hotspot by metro. The is also a little square with taxis and many buses passing by. The local restaurants are cheap and the food is good. The apartment is very clean and as long as you follow the rules of the house you won't have any problem. Since the area is busy, you might need to use ear plugs that are available at the pharmacy on the other side of the street. Guilherme is a great host. He made himself available to help us in anything we needed and gave us nice suggestions about what to do in Rio. If you don't look for something fancy and pretentious, if you just want a safe, affordable, clean and well located place to enjoy Rio, I definitely recommend to book Guilherme's place. It was my first experience with airbnb but I couldn't expect any better. Enjoy it
