Jack the ripper tour is really cool too they leave from near tower of london for about 10-15 pounds...
Just walk or tube there is so much history in any part of london...
Bath/stonehenge is worth the trip too...
Walk from westminster through west end upto soho and convert gardens...its well worth the effort almost 4 years ago
Have heard really good things about them and best of all, its small groups which can be tailored to take in the highlights that you want.
Walking around is really easy in London, or use a mixture of walking and the bus to see a lot more.
For me, the highlights of London are:
Tower of London
British Museum - which is free, but also worth going to see the Viking Exhibition that's currently on
Covent Garden to people watch
An art museum such as the Tate
I loved the South Place Hotel but its not cheap. almost 4 years ago
There are most tourist attractions in London like -
British Museum, Tate Modern, National Gallery, The London Eye, Madame Tussauds, The Tower of London etc.
When the night falls, London becomes more vibrant than ever. You can go to Club Aquarium, The Blind Beggar Pub, The King’s Head & Eight Bells
