Location: it is the best thing about this apartment. 10 min walk to Costco and Chedraui. It is safe area though a little bit deserted in evenings. 12-15 minute walk to beautiful and free Soumaya museum (went twice), two aquariums (visited), lots of shopping malls (visited as well).
Building: building looks like 70-80 years old or even more. It has no elevators, you can climb quite narrow staircase to 2nd floor apartment. Doorbell doesn't work, no concierge so you can miss delivery service. It has beautiful marble staircase and aura of Spanish colonial architecture. We didn't see any other people in the building.
Apartment: good for family with two teenaged kids or even older if they don't mind sharing one bed. Main hall has some soft couches, some of them are too soft if you know what I mean. There is a bar area with selection of wine glasses separating main room and dining area.
TV on the wall is not huge, not very smart, you can watch Youtube but it is impossible to watch Neftlix etc. Very high ceilings. Ceiling lights are not very bright, kids thought they looked like from horror movie.
Two bedrooms, lots of space. One bedroom has a walk-in closet / service room. Cheap shelves from MDF. No washing machine, kitchen has a toaster, drip coffee machine, lots of kitchen utensils. No fans or AC though kitchen area has a ceiling fan - hard to reach to switch on, but it works.
Beds were very nice, bed clothing was very good. There were two faded antique lamps in dining area. Floor has tiles all over apartment, not very comfortable to walk barefoot - you will want to bring your slippers for one reason or another.
Toilet and shower are combined. Huge area with little in the means of shelves. No toiletries except toilet paper and some towels.
Hosts: Very caring. Very responsive - we could arrange extra cleaning same day.
It is a good apartment. Great location is offset by good old apartment with its own quirks.
We used this apartment as our base to explore museums, we visited volcano. Recommend if you are not afraid of all pros and cons of antique apartments. It has its style — its for sure.
