Sissi and Pedro are the friendliest and most welcoming couple. My stay in their appartment felt more like I was staying with friends than that I was renting a room with stragers. They helped me with whatever I needed to know in Rio like transportation, sightseeing, restaurants, safety etc. The room is big, the bed is very comfortable and there's a good private bathroom. It's a large, old appartment, which I like very much, and the location is perfectly close to Copacabana beach, subway, buses restaurants and pubs. The subway connects to most of the major neighbourhoods and with only 2 lines is easy to figure out.
I definately will choose to stay with Sissi and Pedro anytime. I highly recommend their place to anyone who wants to feel at home in Copacabana.
