I really enjoyed my stay at Casa de Aire! They were there to greet me and take in my bag at 12 am when I finally arrived as well as at 5:45 am the day I left. They were always present and friendly, which made me feel very safe during my visit (I'm a single female who was travelling alone for reference - in case there are other solo female travellers who'd appreciate that info!). I saw some other people comment on the noise - I brought earplugs after seeing those reviews but only used them once or twice while there - I'm a sound sleeper but found that closing the sliding glass doors/windows at night did the job in terms of keeping the noise level down. Someone commented on construction noise - there is that going on as they're still working on fully building out the other units in the building (i.e. it's temporary), but there was never construction going on later in the evening or early in the morning so it never disturbed me. I was gone all day but back by 8/9 pm every night and it was never once a problem.
I loved the location of this place, felt super safe staying there, and was really happy with the service and support I received during my stay. I would definitely recommend to a friend or come back if I visit CDMX again in the future! :)
