The Casai staff was extremely responsive and helpful with everything, from arrival to questions to printing a couple of documents for me. It’s great to travel knowing that someone is always there to help. The apartment was spotless and secure (24 hour friendly security staff). I will mention that the apartment is small, though I think that’s clear in the photos and common for CDMX. But otherwise we had a nice stay and thankful for the professional service. Gracias!
