I had a great stay at Nora's location. I spent just under a month in the unit and was very comfortable the entire time. Nora and her team are excellent communicators, and frequently were in contact to check on me. The cleaning crew were lovely and kind. The location is great - right in the heart of Condesa, very near to Roma Norte.
Note: it's pretty common in CDMX to have apartments without heating/AC and for most parts of the year, it's not an issue. However, in winter, CDMX can be quite chilly and as such, the apartment was quite cold in the mornings -- I'd suggest you bring some warmer clothes than expected. Nora did provide space heaters and blankets, which were great, but I did have to layer up.
The apartment also comes with filtered water (a plus!), a comfortable shower, and the patio is quite nice. The building is quiet and clean as well. There is no washing machine, but Nora directed me to some laundry options in the neighborhood which were quick and attentive.
Absolutely would recommend and would not hesitate to stay again!
