The Bnb is well located close to the center of Coyoacán. It’s possible to walk there easily (like in 10-15 minutes) and it feels safe. If you’re traveling by car you can park inside the courtyard. Norma was nice and helpful.
The apartment is nice but could use some maintenance, especially the bathroom was a bit moldy and it’s very tiny and not really comfortable to use. The rest of the apartment is ok and can be a good base for a few days exploring Mexico City. Coyoacán is an amazing neighborhood so it’s definitely a good choice to stay at Norma’s place.
