Elena was extremely helpful - and quick to respond to requests - both with our arrival and departure in flexing the times a little. Alfredo the cleaner was also very helpful in assisting with our taxi and luggage on departure. The apartment is a lovely space and is great for flexing for different combinations of guests. This is a quiet building with secure access from the lift. You could not have a better location in central Coyoacan - and three floors up there was very little awareness of noise from the park behind.
