I also recently stayed at this 25hours and I share most of your comments. Upon arrival I received the same 'upgrade' but I was also offered a welcome drink voucher and in the room was a kind note and a bag of haribo sweets.
Breakfast on the other hand was chaotic since the hotel was fully booked and the breakfast room was heavily understaffed. Only one person who had to cook and serve the guests and clean the table. This resulted in a lot of dirty tables and an almost empty buffet.
Apart from that, I really liked the hotel, especially the living room with the retro turntable.
PS: there is also a branch of the restaurant downtown. I ate there and it was great!
