Our own glass castle in the sky! We traveled as two adults and two young kids ages 3 and 5 for a week. As others have noted, the location is convenient, building is super clean, the doormen so helpful and friendly, and the views are stunning. It was rather fun seeing the apartment from the Castillo in Chapultepec!
While the floor to ceiling windows offer gorgeous vistas, the apt can feel like a greenhouse during the day even with the shades down. As for the traffic noise: as long as all the terrace doors are closed shut, the sounds turn into white noise, which helped us sleep, actually. However, when doors are open, the traffic noise is quite loud - even 12 floors up. Still, we were out and about most of the day so none of the above bothered us too much!
Be sure to grab some quesadillas and gorditas from the street stall located around the corner and halfway up the block on Zamora!
