The room (which was apparently recently renovated/renewed) was very clean and modern. The glass walls in the bathroom are not my cup of tea, though. Some minor noise from the corridor and other rooms, but no real issues with the soundproofing. The Wi-Fi was free and easy-to-use, but the reception in our ground-level room was very poor. Also, there seemed to be some issues with electricity, managed to black out the whole room by adjusting the air conditioning - the main switch next to the door helped to get things back in order.
Location was quite nice, arrival/departure with trains was easy. There seemed to be several cafes right nearby, but couldn't try them since all of them were closed during our visit (the whole city was quite a ghost town during the first days of the year).
A special mention for the very good and welcoming customized city guide given at the check-in.
