Have stayed at a handful of Casai spots. This one, like the rest, is very well appointed and comfortable. Great location; easy check in; plenty of building security; and stylish apartment.
Casai has a bunch of units both in this building and elsewhere in the city. We stayed in a similar unit in the same building but thought it was the one with the balcony. We were wrong. Still, the stay was very pleasant.
Definitely would consider for a long stay given the quality of the internet, the location and quality of the unit itself.
Definitely recommend for anyone who wants to be pretty central in CDMX without being in the messy clusterf*ck that is La Condesa.
