Lovely small apartment in the heart of Coyoacan. It's secluded from the street, so it was quiet and we had zero concerns regarding safety.
Monica and Mauricio were very friendly, flexible and responsive and Mauricio welcomed us personally for check-in.
Coyoacan is definitely worth a visit with the Frida Kahlo museum, the Ciudad Universitaria, the market and the lively central square.
However we decided to stay more centrally located to explore the city center as well as Roma and Condesa as these areas are a bit further away.
And just flagging this for people with asthma: this might not be your best choice, since it's quite humid.
