Lisa's place is everything everyone else has said - SUPER close to the tube and right on the main street. If you're concerned about noise, you'll be relieved to hear that the bedrooms are at the back, so you don't get that noise at all when sleeping (+1 for the active surveillance!) Her house comfortably accommodates us 4, and there was every facility to make your stay easier. It was a great 3 nights spent in London and her flat really gives you the London flat experience. Mind the stairs, though!
