PPR mandatory by phone, but fairly quick and easy to arrange. VFR arrival/departure via specific waypoints. Quiet when we arrived but busier with flight training on departure, including instrument approaches - this is a centre for commercial pilot training. The tower direct you to Apron 4 where you can park at your discretion, then walk to the Hässlö flying club where you can exit - make a note of the door code before exiting. The club has a cafe but I met no admin staff and found that landing fees are paid by bank transfer to the airport - you have to email operations with your details and address so they can post you an invoice. There were roadworks outside when we visited, but we took a bus into the city which was definitely worth a visit.
