I stayed in Roger's apartment only for three nights with a friend -unfortunately- as Roger was a really great host and extremely helpful. He gave us a lot of advice, no matter if regarding sightseeing, safety or restaurants.
The apartment was clean and perfectly located, just one block from copacabana beach and surrounded by shops, bars and restaurants. Nevertheless it is a small and rather calm street, so no loud noises to be heard.
It was a great stay and it is most likely that we come back to Roger's place on our way back next month. Highly recommended!
