We stayed at Fabiola’s for a few days in January. Fabiola is very kind & responded to our messages in a very timely fashion. Browsing the internet on our phones worked fine as well. Fabiola has put a lot of boosters around the fairly large apartment so I suspect the signal is strong everywhere (we were on the terrace). Some city plumbing work was interfering with the pipes during our stay, but it was possible to take a quick hot shower. Our room did get a bit cold at night, but that’s going to be a general feature of CDMX homes & we had plenty of very fluffy blankets. Great neighborhood as well!
Overall definitely recommend a stay!
