This place is in an excellent location steps away from a famed cantina and great food, people watching, street performers and restaurants. Our host was accommodating, thoughtful and quickly (I mean seconds) responded to questions we had. The apartment has a small garden perfect for coffee in the morning and relaxing in the evening. The housekeeper was available to help with anything we needed. I would definitely book this place again. As far as security is concerned, as a foreigner I felt safe and secure in this area of Mexico City even late at night. The area is lit and people are out at the local restaurants late into the evening.
To sum this up-great host, great space, good price, walk to everything in Coyoacan or take an Uber into the rest of the city.
