Nicholas is a great, friendly host and the room is as advertised. The location is super convenient and literally right next to Mortlake Station. If you're looking to do research at the National Archives this is ideal accommodation. It only takes a 30-minute scenic stroll along the Thames to get there. If you're a very light sleeper be aware that there can sometimes be noise from airplanes over head and trains pulling into the station. I didn't find this to be a problem though.
