I didn't really met Maria since she was away that weekend. We were constantly in touch through Airbnb message system and Whatsapp. She was always kind enough to answer my questions and concerns.
The place is as nice as it looks on the photos! The area is perfectly safe and is great to move around this huge amazing city.
The apartment was clean and is great if you like to start your day really early and come back at night.
The small downside is that if you are a light sleeper you might not get a good night rest. There's a school right across the street and the apartment is located with street view which sometimes can be a bit noisy during rush hours or school hours. The place is amazing and this is the only thing I could share I am, sadly, a light sleeper but I still enjoyed staying here and would most definitely come back.
