I had a great time staying in this apartment – it's a cute little, and very tidy and clean 1-room-apartment, right next to the castle. Everything you want to see is accessable by foot and while it's a quite busy area during the day, it's surprisingly quiet during the night.
The only thing which can be improved is the key pick up/drop off, as you might get in distress if you have to leave earlier in the day (drop off shop wasn't opened until 9.30am).
