We spent a really nice two nights at David's place. The area is incredibly convenient - a double-decker bus departs from just down the street, and is a great way to see the city if you see in the top front row! We walked to and from King's Cross quite easily. The flat is modern, clean, and has a very spacious kitchen and patio if you want to cook and eat in. We could hear the faint sound of the subway/train going by from inside the flat, but it was a subtle hum, and I slept very soundly. David was quick to respond to questions, and made us feel very comfortable and welcome. Highly recommended.
