Mario's place is situated in a VERY good location with super easy access to restaurants, coffee shops, Metro and other trendy neighborhoods such as Roma and Polnaco. You can also easily access the beautiful Bosque de Chapultepec park, Museo Nacional de Antropología and the Chapultepec Castle which are all totally worth seeing. The Historic center of Mexico City is just a quick Uber ride away or you can also take the Metro. Mario is a very pleasant and easy going guy who also provided local recommendations. The place is described pretty well in the photos, however, I do think that the cleanliness could improve to make it a bit more comforting. Overall, had a good stay and really enjoyed CDMX!
