David's apartment is a nice little spot where I had a largely comfortable stay. It has just about everything you might need and has an unbeatable location (walking distance between many popular and useful spots, great transit connectivity, and services of all sorts right at your disposal). The apartment feels spacious with its high ceilings and distribution and was quite comfortable. The kitchen is small but did not feel cramped and was quite well equipped. The mosquito net over the bed while staying in the depths of the rainy season was a lifesaver and made my stay that much more pleasant. The building is older but relatively peaceful. The water pump operating in the wall may confuse you the first time you hear it but it isn't so frequent or intrusive. The neighbours are largely quiet - understanding that for the architecture of such buildings its impossible to carry on the normal life of children and conviviality and not hear it elsewhere through the back of the building onto which the apartments open. As well, if like me you are driven mad the general custom in Mexico of doing nothing to train your animal and resultant incessant barking, there is a dog in the apartment right at the front door who will bark when you come and sometimes besides, including in my case once for an extended period at 03:30 in the morning that woke me up. David, though, was a very attentive host, and I don't know if through a Whatsapp group with neighbours or how else learned about that experience (the dog barked long enough I had to go down and ask them to please take care of the animal, though I didn't care to bother David with the annoyance) and apologized and let me know the neighbour would be more conscientious with their animal. As that might suggest, communication was easy and prompt, just like check-in and check-out. Among all the many apartments from which one could choose in Mexico City, I felt that David's was well worth it!
