Had one night here in late March before travelling on further south. Views are excellent of Berwick and the sea but it is by the east coast main Line although the trains are not too noisy. Also the approach is through a built up area of houses.  Berwick is worth a visit and it is only 20 minutes down the A1 to Lindisfarne.  There is a retail park near and a very good fish and chip shop called Roberts.  The wardens were very welcoming and the site immaculate. The toilet block was spotless and nice and warm.   Would use again as a stop off if travelling up the east coast but wouldn't think it is a base for a longer holiday
