If you are hesitating to stay in Flavia and Mauricio's apartment, don't. It is everything one could want - very central (about a 5 minute walk to the subway, and in a great neighborhood itself), clean, modern, and well-decorated. There is a security guard downstairs 24/7 who allows for the possibility for off-hour check-ins (like ours) and who adds a layer of security to the building (which is already in what seems to be a safe neighbhorhood). Flavia and Mauricio were always avaialble by messaging through the AirBnB app, and replied very quickly to any message. Would definitely stay with them again!
