the apartment was in a great location and the beds were super comfortable! We were there in December, and the apartment (like so many) was really cold inside (which again, is really common) - so we massively appreciated all the cozy blankets and pillows for the beds. We all slept great, showers worked well with a decent supply of hot water (not always the case in Mexico City!), the kitchen was very well stocked (with only one exception - no coffee or teapot!), the living room super comfortable with a gigantic couch.
The check in process was more annoying than it needed to be, as I wasn't given instructions on how to get inside the apartment despite asking repeatedly. It wasn't complicated at all once we called the host (twice - who luckily answered right away), but carrying a sleeping 4 year old and a bunch of suitcases and not knowing how to get in was frustrating. for future guests: Make sure you ask the host to explain to you where to find the doorman (it's not super obvious from the outside if you're arriving tired), make sure you get the code for the apartment door and make sure you understand how/where to place your hand on the apt door so that the keypad shows up. if those things are clear to you, you'll be all set. Whenever you enter the building you may need to tap on the window of the doorman, and it's important you know to do that and where to tap!
The stay was great and now that I know how to get in, I'd stay again with zero problem!
