I really liked this apartment. Karen was very easy to coordinate with and left some treats at water/juice for us.
The only negatives for me was the bathroom. It's a LOT smaller than we expected it to be - the vanity is really tiny so it's hard to actually brush your teeth/wash your face without splashing most of the water on the floor! And the sliding bathroom door doesn't close properly - you need to lift the door in order to sort of close it with still a good 3-4 inch opening. So if you are travelling with friends/significant other, be prepared to get comfortable real fast!
For the 2 nights we were here, it was really loud outside around 12am-1am ish. I think garbage removal happens in the middle of the night and the walls are pretty thin, so you'll hear the neighbors.
