Norma is absolutely a wonderful host! I had a late check in with a same-day booking. She was so flexible and responded so quickly. The place is comfortable. Just what you need for a night: a soft bed and a clean bathroom. We had some problems with electricity, but that was in the whole area and pretty common in Mexico. Wifi works, but just for the little things to do on your phone (in my room, perhaps in another room it will be different/better) + great location! I would totally recommend it if you'd like to stay in Coyoacan.
