The flat was just perfect. We really enjoyed staying there and would definitely recommend it. It was suuuper clean and tidy, well equiped, comfy bed, good shower, nice towels, ... everything you need. It almost felt like home. Late check in was easy and our questions were answered really fast.
The location is great, when you like going to the city center! We did some excursions and catched trains - the walk to the train station can be a bit tiring, but if you like to walk it'll be fine.
