Kate is a great host! She was incredibly flexible with checking in and out, and she is very easy to communicate with. The location of the apartment could not be better, this area is really nice. The room is also clean and pleasant, and it looks exactly like the pictures. Also: the room is completely silent and peaceful at nights, even with the window open.
I stayed here for six nights, and for someone looking for a longer stay I would point out that the room really is very small (as shown in the pictures), which can make it difficult to unpack your bags and so on. There is also a shower inside the room but the water pressure is really low, which can be frustrating at times. However, I was very happy staying here for six nights, so I definitely recommend this!
