Nice apartment in a good location in Polanco, next to museums, Chapultepec park, and great restaurants. The host was friendly and responsive.
The stairs leading to the apartment are a bit scary because there is a part that has a 6 ft drop with no banister. If you have balance issues, that part of the stairs could be a hazard.
Unfortunately, the water heater was not working properly. The first night the water was luke warm, on the edge of uncomfortable. The second night it was ok, and the third day it just stopped working altogether.
The host was courteous and tried to help, but was not able to solve the issue. I cancelled the rest of my reservation, and the host was very gracious in refunding me the remaining nights, and providing a small discount for the days that I stayed.
