Overall we were very happy with our stay. The apartment is quite large and comfortable, and we found the apartment matched the description and photos (quirky, homey, surprisingly little airport nosies).
That being said, on our final night it was nearly impossible to sleep, because the sounds of somebody walking and running (skipping?) in the apartment above... between 10:30 and midnight the floorboards would creak as somebody moved back and forth from one end of the apartment to the other (to right over the bed, as it happened). I’m great at sleeping through white noise or even ambient party sounds, but the creaking of floor boards right over my head was very difficult to get past, especially with the run/walk/what the heck is happening aspect. I’m sure if I lived there I would get used to it, but as a short term stay, it was disconcerting to hear floorboards creaking in part because it sounded like there was somebody *inside* our apartment. Also, I personally didn’t wake up for it, but my husband said there was piano playing in the wee hours of the morning as well. That being said, every other night it was SILENT in the unit above.
