Juan's place is cute and clean. Roma Sur is a great neighborhood that is a bit less touristy and is more quiet/calm than Roma Norte and Condesa, both of which are easy to walk or bike to. The close metro and bike station are great, as is the park. Overall I liked the place. I think it is a bit expensive compared to many other comparable places I've stayed in CDMX, and the kitchen could use some basics like salt, pepper, olive oil, etc. Overall a good stay.
