Used the site as a base for a short break in London.  Excellent location.  Easy to get to from M25 and Denham station 5 minutes drive away.  Just over £13 for an off peak return to Marylebone complete with all zones tube. Or allow half an hour for walking to the station plus there are a couple of buses from the site to the station. We weren't expecting peace and quite given the proximity to the M25, Heathrow and Denham airfield.  So there were no nasty surprises on that front.  In fact the main noise was from helicopter traffic.  But didn't cause us any problems. Some of the pitches are quite compact.  We have a fifth wheeler and there would definitely be some pitches we wouldn't be able to get on to.  But all are level and gravelled. Facilities on site absolutely the tops.  Some of the best toilets and showers we've experienced. Really great site wardens who were very helpful.  They had compiled a nice circular walk from the site to the nearby canal and a pub that serves good food, especially Sunday lunch. The site met our needs perfectly.  It's not the place to go with young children (unless it's just a sleeping base) or if you're expecting masses of space and greenery.   As mentioned by Lynndy, the roads around the Denham area are absolutely appalling.  Take it easy and watch carefully for pot holes!! Will definitely use this site again for any London trips.
