Nice space in a wonderful neighborhood. I personally enjoyed the piano, which you can play during the day. Very quiet space, with only Claus living there, and big windows overlooking the park of a school next door. Great if you want a nice place to stay in Coyoacan, with a quiet atmosphere, and green views. Claus is an interesting person to talk to, working from home on a phd, and with an interesting and unusual. job (I'll let you ask). One of my fave cafes I think in Mexico city is just down the street - el Beneficio.
