Communication was EXCEPTIONAL--the Casai staff always answered questions and resolved any issues that came up. Wi-Fi was excellent, and the filtered water was key, since you would otherwise have to buy. Location was EXCELLENT! Great restaurants in area, and if you're a coffee lover, be sure to try Cardinal right across the street. Also, the building could be hard to find if you're not familiar with the area--it is on Calle Cordoba, across from a building with pink paint--numbers 131 in red, and it's a black gate that you ring the doorbell. It's very easy to miss! The security guards are fantastic and the area and building felt very safe!
