Rosalia and the Casai team were incredible hosts! Their communication was responsive and top notch, from the moment I made the reservation to the moment I checked out. When I had a small issue (dead batteries in a remote), they responded immediately and had batteries waiting for me at security when I came back at the end of the day. The security staff was super friendly and were always prompt in letting me in the building. I actually teach customer service professionally, and Casai’s service was impeccable. As for the location… The apartment was clean and in good order. It looks like the pictures. Small, but modern and well furnished. (There is no elevator, and this apartment is on the third floor, so be aware if that is an issue for you.) The location in La Condesa is excellent! You are surrounded by food, cafes and convenience stores in the immediate area (including a Starbucks, a two-minute walk away). More importantly, the best parts of La Condesa, an absolutely amazing area, are all within ten to fifteen minutes by foot from the apartment. I highly recommend this location in particular and, because of their attentive service, any other location managed by Casai!
