Noisy!
Never slept as bad as here: the folks in the upstairs apartment are walking around at any time of the night, and while they are just acting normally the wooden floor is incredibly thin and squeaky. First night we got woken up at 2am and heard them wandering around for over an hour, other days it was 4am.
We lived in a multi-family apartment in Mountain view for a few year and never had this problem that bad…
Another minor thing was the kitchen appliances and the kitchenware that was not clean. It was’t terrible either but not very pleasant.
