I was on a business trip with three colleagues. I express the general opinion. Minus the score for sound insulation. You can hear all the neighbors located in the rooms on the sides and above, especially at night. Fans of a good view from the window will be disappointed. The maximum that can be achieved is a view of the lovely courtyard that is used for smoking. However, the smells from smoking tobacco and cooking can spoil the impression of your stay.
In all other respects, the hotel is of standard European quality. A delicious and varied breakfast at a nearby restaurant. 10 minutes walk to the center and 2 hours by train to Amsterdam.
