This ain't the Ritz, so don't expect it to be - don't look for luxury here. It's a totally acceptable and simple private refuge in a crazy city. The location can't be beat: at the end of a short private street (very quiet), and easy walking distance from anything in Copacabana. Sergio is a fine host, and very responsive. If you let him, he'll tell you all about the city and give you lots of recommendations. I did more than half the stuff he recommended, and all of them were great.
