The apartment was perfect for our family vacation. We had 8 in our party (4 adults and 4 teenagers) and the space fit us perfectly. The location was also perfect for our teenagers who explored the neighborhood on their own, going to the cafes and enjoying the sights and sounds of the Condesa. The localappleCO team was responsive when we needed a space heater for the cooler than normal nights in late December and they were also extremely helpful with helping us organize transportation for a day trip to Teotihuacan (this was huge).
Re sound/noise level. We arrive on a Friday evening and during our 5 night stay, it was for sure the nosiest of all the nights. Ear plugs worked for most of us but be prepared. If you're down for the party then you will be just fine, if you want a something with a bit more tranquility then I recommend to stay away from the weekend party. We found the weekdays to settle down a bit and noise from the street subtle and normal/expected for a busy neighborhood.
