The apartment is in a great location. It appears as in the photos. There is great light and it is nice to relax after a full day of walking. There are so many good restaurants near by all within walking distance. We enjoyed just walking around and getting a feel for the neighborhood. We also walked to the metro station about 10 minutes away. Very easy to use & extremely cheap. Just be careful during rush times as the cars may be too full. Uber from the airport is good too - depending on time, very inexpensive.
Hernando was an excellent host. He was there to help us upon arrival and offer suggestions. As others mentioned, he is very helpful arranging for a driver to Teotihuacan to see the pyramids. This was much better than taking a bus as you can come and go when you want and not be at the mercy of a tourist bus schedule. He is a very nice person and very responsive.
