EBOS. Trains from Oostende to Brugge about every 15 minutes. Only bad thing is connection EBOS to train station, which needs a bus or tram ride.
Ursel is indeed shorter in distance, but no easy connection to Brugge, and difficult opening hours of airfield (military).
Unpublished frequencies, downwind landing never had a problem with these in 10 years of Belgium flying. Poor handovers may occur in 1% of the cases, some controllers expect that you know where you are and expect you to avoid certain areas by yourself. Bru info will always help you when in doubt.
