We stayed for three days in April 2016, and cannot recommend Villa Alfonsina highly enough! Minerva and her family are incredibly gracious and helpful hosts, and their beautiful home is located in the wonderful neighborhood of Coyoacan, conveniently located near many bars and restaurants. If you are interested in seeing the pyramids at Teotihuacan, definitely take a tour with Minerva's son Hector. We would not have enjoyed them as much without his knowledge and experience. The next time we have an opportunity to go back to Mexico City we will absolutely try to stay here again!
