This apartment has the best location in City, right at the meeting of Condesa, Roma Norte, and Hipodromo. So many cafes, restaurants, and parks within a few blocks in all directions. The place is very clean and has simple but stylish décor and the kitchen has all the supplies you need (if you can convince yourself to not go out to eat for even one meal!). Bed is comfortable, bathrooms are clean, and there is a ton of closet storage space.
WiFi is reliable - I worked here for a month with many video calls and only had one or two calls drop for a second. The desk set up by the large window and balcony was a perfect remote work set up.
It was a little chilly (I was here in February) but I found if I opened the balcony doors occasionally while working during the day it would warm up, plus wearing slippers around and having a sweater handy worked fine. There is also some noise in the bedroom at night coming from a nearby apartment or building. I brought a small white noise machine that I used at night and didn't have any trouble sleeping. From reading a million reviews of AirBnBs before settling on this place, both of these issues seem to be are fairly common in CDMX apartments.
Marlene was very communicative and responded quickly whenever I sent messages. The apartment feels extremely safe and the doormen were very friendly and helpful as well.
I would definitely recommend this place. Although it is a little on the expensive side, it had everything I needed, was safe and clean, was good work environment, and in a great location--I didn't need to worry about anything.
