The apartment was squeaky clean and neat. The location was perfect for my purposes. The hosts were quickly responsive to my initial concerns.
That being said, those concerns could easily have been avoided with more complete and explicit instructions beforehand (e.g. how do you turn on the lights in the bedroom; what do the switches in the living room control).
Noise isolation from the adjoining units was not ideal. Since I was out most of the time, this wasn't a problem for me personally.
