Location of the apartment is excellent, it is safe to walk at night, you have a mexican market just one block distance, restaurants, asian supermarket, museums, it is close the the CDMX Arena (Wrestling events!), also close to Reforma which is the central line to take the Metro Bus to other places.
Ulises is a super host! He is friendly, quick to reply of any needs, have good recommendations of places and food, he also gave us Tamales the last day we stayed at the apartment!
Totally recommended 5 stars!
