Minerva and Hector Sr. and Jr. were wonderful hosts for our four-day stay and made us feel very welcome. They're also happy to offer recommendations on food and sites, and are able to arrange taxi service all over the city for you. Villa Alfonsina is a beautiful, clean place in a great location. The rooms aren't huge, but you certainly get nice, high-quality hotel style rooms at a fraction of the price, and you'll see a bit of Mexico you would not get to otherwise. Highly recommended. If you're not that familiar with Coyoacan, it provides a nice respite from the hustle and bustle of D.F. proper.
