Small dark rooms, poor breakfast
My 'superior' room was small, poorly lit and did not have proper windows (a small window at feet level and a small one by the ceiling!) The bed was comfortable although I was provided with a better pillow. The breakfast was awful.
Positiv: good central location, comfortable beds and spacious good shower; Negativ: tiny windows, room im basement with lot of noise from reception and bar, parking is around 5 min walk away and with 18€ not cheap, sauna might exist but you need to call before to use - for day of arrival not an option
Friday evening in Groningen
I can recommend the place. Room ambiance a bit dark, with low power lights and small windows. But otherwise very good. Large bathroom, spacy room, very good bed, armchair, possibility to make an espresso in the room. I'll use it again, definitely.
