Together with my partner I've stayed for one week. We loved the big balcony with the stunning view over the park and town. The location is ideal, only a short walk away from the city centre. Next to the building there is a bar and a coffee shop. Internet is good for working remotely.
Hospitality could be improved a bit in our opinion. For example by providing more than one cup of coffee per person, some kitchen facilities and an extra towel for guest that stay multiple nights. The list with fines hanging on the wall doesn't come across as very welcoming: 30 euros if you forget to put the bin bag outside or 30 euros for a make-up stain on the towel (never knew IKEA towels were that expensive).
If you come in the winter, bring something warm as the appartement can get quite cold. Overall we had a good stay, so I would recommend this place!
