Small, but great!
We stayed at the hotel for three nights during a short December trip to Groningen.
The room was small but nice — and the same goes for the fitness centre, the breakfast buffet, and not least the hotel’s private parking garage: all of it small, but perfectly adequate. However, if you’re arriving by car, I would recommend using a public parking garage instead, as the entrance to the hotel’s own garage is very narrow.
On the other hand, the hotel’s location is excellent — right in the city centre, within easy walking distance of everything Groningen has to offer. In addition, the staff are very friendly, kind, and helpful.
All in all: small, but really good!
