We are thinking of a trip to London this summer with DD(9) as she wants to see some sights and go to Hamleys. There is a chance we could stay at a friends place in Tuffnel Park. Not knowing London that well, is that an ok location to get to the places we want to visit, National History Museum, Trafalgar Square etc? Or would we be better off looking for an air bnb or something. Bearing in mind friends place wil be free. Thanks.
