Really easy to get into London from here.  Bus to Hatfield station then train to King's Cross.  Hatfield House was brilliant and well worth a visit as its so close by, with wonderful walks too. Also recommend a trip to beautiful St Albans. The site was fine, though apart from booking in we didn't disturb the staff at all as they don't have a 'shop' and there was nothing we needed from them.   There are a few shops about 5 mins away for papers etc.   The showers at Commons Wood, however,  are awful.  So bad in fact that it was easier to have a strip wash and use a jug for my hair.  I could dribble more water! We enjoyed the break and would certainly use the site again if wanting to visit London and the area.
