Christopher's airbnb is in a great location (5 mins walk from King's Cross, and in a safe neighbourhood). Christopher was very flexible about our arrival time and was extremely communicative and helpful. Room is exactly as pictured, and was clean and comfortable (warning: it's a small room and gets very warm, but the window can be opened). Bathroom was clean and functional.
For the price, it's a great place to stay and I wouldn't hesitate to recommend to anyone travelling to London for a couple of days.
