We really enjoyed our stay at Sergio's guest house. It's really well located in a private safe street. The house is conform to the description and it was nice to share common areas so we have been able to meet other travelers and explore Rio together.
Sergio is very well organized and has been quick to respond to any requests. He provided us with detailed informations about the neighborhood and Rio as well as giving us recommendations about places to visit and restaurants.
I highly recommend Sergio's guest house for a stay in Rio.
