Communication with Jean was fine before and during our stay by e mail but we have met anyone during our stay (check in done by doorman who gave us the keys, check out by leaving the keys in the apartment).
+: very well located apartment (5 minutes walk from the Copacabana beach, supermarkets and bus stops, 10 minutes from 2 subway stations), quiet apartment, secure (presence of a doorman 24/24), comfortable bedding.
-: decrepit apartment, cleaning is not well done: the apartment was dirty. Ok for a stay with friends if you are not looking for cleanliness but I would not advise to a family with children.
