I've been there for my sim and passed it. It's of course not as realistic as a real full motion one but it is more than enough to prepare an airline selection.
The instructor is an ex-sabena and the atmosphere is very relaxed. I would say it is the best value you can find and Brugges is amazing!!!
There is a cheap hostel very close to the college (about 15 euros a night).
Definitly a place to recommend!
