We had a truly wonderful time staying at Sofia and Stacy's house. I would recommend it to any visitor, including families with young kids (our son is 2). They've set the house up so thoughtfully for visitors. The decor is inspiring, all the necessities are present, the rooms are comfortable, the kitchen nicer than ours at home, the terrace lovely for hammock naps, bathrooms very clean, etc. We loved returning home at end of day. Coyoacan, though a bit far from central neighborhoods of interest (we took lots of Uber), is such a special place. It's green and quiet, though lively, which can be a nice break from other parts of the city. It's got a truly neighborhood/community feel. You'll find modern cafes and wonderful old coffee shops, along with a great mercado with the requisite fruits/veggies, food stalls, home goods, toys, etc. Lovely town square and park, everything you would expect from a zocalo at night, etc. Cannot recommend highly enough!
