We booked into Abbey Wood with 5 other families/couples to watch some events at the Paralympics. I had wondered what to expect of a campsite practically in the middle of London, but am delighted to say it was needless concern.
The whole site is great!
From arrival through to check out a week later not one of us could find fault with any aspect. Spotless shower and toilet blocks, well spaced across the site, with hot water at all hours. With clean and well maintained prep'/washing up kitchens at each block. We didn't use the laundry facilities but they looked as well maintained as the other facilities.
The wardens were friendly, approachable and informative.
The site is a 5-10 minute walk from the train station (Abbey Wood) and a row of local shops. And 2 minutes from Abbey Woods itself, absolutely great for early morning runs, strolls or dog walks, and the abbey ruins and gardens, with TI centre and tea shop! (we didn't catch the shop or TI open, because we were there and gone before they opened in the mornings, but everything was immaculately kept and looked great)
All members of our large group would definitely use the site again.
