Spent 2 nights here, having come for the Bowie exhibition. It's fairly basic, with no en-suite in the room I chose (but fairly quiet if you ask for a room at the back), but clean. Breakfast included, really just bread and cold meat/cheese, but nice orange juice and coffee. The owner was pleasant and helpful. Probably not appropriate for a woman travelling alone (just to left of hotel as you exit is a very in-your-face red light street, though turn right and you're on a quite elegant pedestrianised shopping street, girls). Groningen was a nice town to hang out in for 48 hours, with very vibrant cafe culture and interesting shops. But apart from Bowie, the best thing I did was get train to Uithuizen to see lovely Menkeneborg manor house.
