Hi was in Mario's apartment for 3 weeks and i have to say
that it is a very good and clean apartment located in a position (copacabana) near to the sea and central , it is a very safe zone now,
i didn't have any problems at all, Mario has a cleaning service in the apartment that comes every few days to clean everything.
I really appreciated Mario's help to learn how to move in rio and how to enjoy my vacation at best.
