Casai was exactly what my friends and I were looking for - some place cute, modern, clean and safe. Located in the heart of Roma Norte, you will find manyyyyy cute cafes and delicious restaurants just walking distance. There is also a 24/7 security guard that opens and closes the front gate so myself and 2 friends felt incredibly safe. The airbnb itself was super clean and comfortable but the only downfall was that there was no AC unit (which may not he common in CDMX as it does not get that hot but be weary of mosquitoes if you open the windows. It was also extremely easy to communicate with the host and received answers to questions within minutes. Highly recommend.
