We found this site ideal when travelling from the West Midlands. We endorse all of the previous reviews, it it very clean and tidy, the Toilets are superb and there is noise from the nearby airfield. If you are going into Central London I would point out that the Oyster card does not apply from Denham station, so be careful. We were advised to travel to Hillingdon (15 mins) by a TFL Station employee where parking was available every day (£6 per 24 hrs). We preordered a zone 6 travelcard which gives unlimited travel within the Oyster controlled area on Overground, Tube, Buses and DLR. Overall, apart from the aircraft noise (Worse at weekends) this is a wonderful site in a nice location.
