We never met Doug, but he replied promptly to our emails and provided very detailed and precise instructions for entry..
The area is very convenient for seeing London but not itself trendy. No restaurants nearby, but the local chippie does great kebab style meat.
The flat was very clean and light, however the bedroom is tiny. The bed is queen sized, and very comfortable, but it takes up the whole bedroom . The listing says lots of storage, but all the cupboards are out of reach - at least 3 meters up the wall. (there is a ladder under the bed )
Still a very good place to stay.
