If you are looking to get away from it all and are travelling with little ones to London then you should rent a car. The city has several points where you can collect your hire car: London Airport, London Crumlin RD, London Railway Station, London Downtown, London Hyde Park, London North East, London York St. and others. Don’t hesitate to ask some of the locals about the best non-touristy places to visit so you can experience London without the crowds.
