Smart Hyde Park Inn- middle of london, right near the bayswater tube station, pubs, shopping and a grocery store. Its around $18 a night, cheaper than 15 pounds. I'm a big fan of the place.
"All men dream: but not equally. Those who dream by night in the dusty recesses of their minds wake in the day to find that it was vanity: but the dreamers of the day are dangerous men, for they may act their dreams with open eyes, to make it possible. This I did."
-T.E. Lawrence, Seven Pillars of Wisdom
