Isabel's apartment was just as described. The unit is located in a great spot on CDMX, Roma Norte, that is easy to get around to all other locations in CDMX. When staying in other neighborhoods like Condesa, it's easy to get stuck and just stay in those places, but the location of Roma Norte encourages you to explore as it's central to most other locations of interest.
For those visiting on business, the internet was reliable and quick enough for sustained video calls using Zoom, as well as VoIP calls using Google Fi.
There was occasional outside noise at night, but it was very rare, maybe once or twice during my month-long stay. Otherwise, very peaceful to sleep at night. Isabel is also very responsive and I never waited long for a reply to any questions I had. Thanks for the great stay!
