It is a nice hostel with everything you want. You are clearly not meant to stay in the dorm rooms for long. But I enjoyed staying in the lobby very much. You can find a lot to do there. Althoug I didn't expect it to become as cold there in the evening.
The location is very handy. You can quickly access the touristy center, but are not thrown in the middle of it and can stay away from the busyness if you want to.
