We had a great week up in London staying at the Abbey Wood site. Highly recommended - it's a great site, wooded with plenty of space. It's a 10 min walk down to Abbey Wood station then just 23 mins on the new Elizabeth line into Tottenham Court Road (modern trains and stations). Easy access for tourist spots, theatres, museums, shops. Really easy access from the M25. It's in the LEZ, so it depends on the age of your vehicle as to whether a charge will apply. Just check the Transport For London website. The wardens were brilliant - really friendly and helpful. Will definitely visit again.
