Not really SE, but Leicester might be worth a try as it has a number of short runways (sub-500m) both grass and tarmac in a variety of directions, and its always struck me as being relatively quiet.
An alternative is to find a nice big runway and mark out a suitably short strip, either by pacing it out or by reference to other features. This will allow you to screw up without REALLY screwing up
For a bit of fun I always try to make the first turn off at Elstree on Rwy26 when 1 up in a C150, guess that's probably about 250m
