The apartment is in a great location (Roma Norte) within short walking distance of a wide choice of bars, restaurants, shops and all sorts of other useful facilities (barbers, lavanderias, street food etc). It is also not too far away from many of the key places you may wish to visit around CDMX. It is 2 blocks from a metro station (Hospital General) on line 3 which proved convenient. I used the CDMX bikes while visiting. You can hire a city bike for a week and there are 2-3 bike stations near the apartment. A great way to see the city and where you actually are going and to explore the nearby area much more rapidly than on foot.
The internet speed is excellent and worked at all times. Useful when needing to do some work or use it or for streaming etc.
The place is very comfy, has 2 nice bathrooms. The bed is comfortable and kitchen good.
I think the owner has ordered a heater. During my stay (Dec 21 - Jan 22) at night some heating was needed. This heater did not arrive while I was there but I was able to heat the place up by using the electric stove.
The place currently advertises itself with parking available. The parking space for this apartment requires that the car is driven onto a ramp and is elevated. My friend's car, while not that big, was too big (tall) to use this as the roof of the car would have hit the ceiling to allow the ramp to be fully elevated and allow other cars using the garage to pass. Most visitors are unlikely to be using a car though as CDMX has great options for public transport.
I enjoyed my stay there very much. A great place to be based in during a visit to Mexico City.
