David is a very friendly and approachable chap. It is a shared house but it was a very workable scenario. I did not feel like we were stepping on toes ... and there were 3 of us. The sofa does turn into a bed but as in most sofa beds the bar running down the middle makes it very uncomfortable. But the sofa left as a sofa is decent. The bed had a decent comfort level. It was in the loft so the hot days this summer left it very warm. There is a Velux window which helped towards the evening at the cooler air drifted in. The location is fantastic, 10 minute walk to the new Elisabethian tube line. For a single person, young couple looking for a reasonably price AirBnB near London, it works.
