The apartment was nice & clean, in a nice neighbourhood.
The highlight, anyway, was Diogo. As we say in Argentina, "Diogo es un grosso". He helped us not only with directions but also with even the most ridiculous requests (of which a toaster was the easiest one).
The place is at walking distance from the beach (6 blocks approx), and also from nice places to have a drink or have dinner.
Also, Shopping Leblon around the corner.
