We thoroughly enjoyed our stay at Lilia's place. The apartment is clean and spacious. The bed was very comfortable. The apartment has two bathrooms, which is a great feature. It is located in a decent neighborhood with plenty of food options within walking distance. And it's a quick Uber ride from pretty much any place you'd want to visit in Mexico City.
The building is safe, and everyone we encountered (from security staff to other residents) were helpful and friendly.
I would note that the apartment is on a busy street and can be a tad noisy (there was also a loud party in a nearby apartment while we were there). It was not an issue for us, but could be for someone looking quiet accommodations.
All-in-all, this apartment is a great location from which to explore a beautiful, lively city. We can't wait to go back!
