correct me if i'm wrong but is Welwyn Garden City not in hertfordshire wich is over the other side of the m25?
quite a treck from central london if your just visiting
we were originally in north London but moved out to Welwyn a while ago.We are about 30-40 min north by train and a 10 min walk from the station which is a very easy trip to make.
Any order can be sent direct to your hotel so if you prefer you don't have to leave the room....
