Alberto, Andrea's father, was very welcoming and helpful. He also made great breakfasts. I saw much less of Andrea and Lolita.
The bed was very comfortable and the room was great. The house is in the leafy neighbourhood of Coyoaocan. However, it's a long way from the centre of Mexican Can't try so if that's where you plan to spend your time, be prepared for taxi or Uber time and fares. There are museums nearby in Coyoacan which are walking distance though. Also good food and convenience shops locally.
