Great place to stay! Marsha was one of the best Airbnb hosts I've ever run across. We didn't get a chance to meet her, but her communication was extremely fast and friendly. She answered all our questions immediately.
The place is in a great location to explore London, with the tube and overground really close. The Sainsbury's in the O2 center (5 min away) has everything you could possibly need. Definitely recommend!
