The apartment is in a great location, however, it is on the ground floor and the front door and the windows open right out to a busy sidewalk and street. This equates with much street noise so it would be helpful to bring some earplugs for sleeping. This is most likely the case in any Mexico City apartment. The city is very noisy and most the time windows are open for air, so again - bring earplugs! There is no air-conditioner, which is probably only a concern in April and May. It was very stuffy and warm while we were there and it would have been nice to have a fan. Communication was prompt and responsive. The WiFi is great. The door locks provided the security needed. The apartment was clean but I don't believe the sheets had been changed. Luckily there was an extra set available. All in all it was just adequate.
