Barking,
I don't know what site Ann stayed on, but I can say without fear of contradiction the Abbey Wood site is definitely, definitely NOT in the middle of a housing estate!
It is in Federation Road Abbey Wood SE2, the front of the site (entrance) is in Federation Rd the site itself is within the bounds of the woodland not far from the site of the ruins of Lesness Abbey, hence the area's name Abbey Wood.
How can I be sure of that info, I lived in Abbey Wood for 20 years, 6 years in Knee Hill Crescent, not more than 100 metres from the camp site.
We moved to west Sussex in 1995 (to be near the sea as my other passion is sailing) but we still go back to Abbey Wood to visit relatives & friends & when we do we always stay on the site.
The site is within the urban conurbation of London & its true to say that the whole area is somewhat run down, mainly due to the looney lefties who run Greenwich borough council, but that's another story altogether.
Don't let Ann's comments put you off, the site is a credit to the wardens & to the CC!
Enjoy your stay!
