London's skyline has been transformed in the last twenty years or so, and although some of the buildings may not be to everyone's taste, it's a city which has something for everyone.

You don't even need to board a plane... which is awesome for people like me who would rather give the stress of the airport a miss if it's only a weekend getaway.
