It was a cool experience but the pod we were in smelled like a foul bathroom, not a smell really, more of a presence. We thought they went in to clean between visitors but they were checking for bombs? And they did a really half hearted cleaning job. You do get a spectacular view of London, you can see everything from there but there's always the "presence" and apparently a chance of bombing.
