The site is immaculate and the toilets/shower/washing facilities absolutely spotless. Aircraft (helicopters) noise was not a big issue for me but I can understand for some it would be. Easy access into central London by mainline or tube, close to the Grand Union Canal and Colne Valley Park, and Denham Village visit a must if you remember the old Agatha Christie films where a number were shot. The temporary wardens were helpful and friendly and as the site is outside the low emission zone and open all year, for my purposes it was as near perfect as I could hope for.
