Everything was exactly as expected, just great! We had 3 days in Mexico City when our flight was delayed and Guillermo was able to accommodate us last minute—plus it's very close to the airport and walkable to just about anything you need.
Bed was comfy, WiFi connection was nice and strong for my Zoom interview. The place is spacious and laid out very nicely. Would definitely recommend his place to anyone visiting the city, especially if being near the airport is important for you!
