I absolutely cannot recommend Sergio´s place enough! His home is very nice and clean, and while he makes you feel very welcome in all common areas of the house, your room upstairs has plenty of privacy and a wonderful view! The neighborhood, Copacabana, is an excellent home base for visiting Rio´s biggest attractions, and public transportation is very easy to navigate (Sergio is also very helpful - he wrote out excellent directions and instructions for buses and the metro). There is no wifi, however Sergio´s computer with internet is available, and there are several cafes nearby with free wifi. As for your host, Sergio is charming, warm and intelligent with an excellent sense of humor! He is very knoweldgable about his city and is willing to share as much information as you would like. I am so glad to have met him, and would highly recommend a stay at his home in Rio!
