For a group of 11 college students visiting Mexico City for a week, Abraham's casa was absolutely perfect. As for Colonia Guerrero (the neighborhood), we saw families out on the streets all week and there's a preschool two doors away, so it seemed perfectly fine to us. The subway is very close, plus, Parque Alameda and the Centro Historico are easily within walking distance. There are excellent bakeries, a tamale vendor, a very good birria & pozole restaurant, and an outstanding taco stand just steps away (the latter are open late, so finding an excellent meal was never a problem). The students loved the many levels of the house, with its multiple private and public spaces and terrific rooftop deck. On top of all of that, Salvador's and Abraham's responses to any questions or issues were some of the fastest I've seen on Airbnb. Their hospitality is top-notch! Just a terrific place to stay in so many ways.
