A nice hostel, I'd stay...

Liked: the room was nice and warm, the bedding and towels were fine. the checkin procedures were very easy and the receptionist was very helpful even though we were only in contact by email. the kitchen facilities were very good, and I'd stay again and cook my meals there (we went out for dinner but it is good to know there is a good kitchen for our next stay). The location was very handy for the train station, and there is a great polish bakery/cafe just across the road on the way to the station.
Disliked: it was a bit frustrating that the other guests kept propping the inner security door open despite the signs saying to keep it closed, as it seemed a bit of a security risk. Not a negative but a note: there is no secure onsite parking despite the impression I got from booking.com (there was a Parking icon in the facilities list for the hostel). However there is off-peak parking on the residential streets behind the hostel and very good value 24-hour parking in an unsecured lot just across the road in front of the hostel, so it worked out well.
