I had a great stay for four nights at Nicholas' apartment. The apartment is located conveniently close to the National Archives and is right on Mortlake Station, making it easy to get around. Nicholas was a great host, making for a friendly, relaxed and comfortable stay. I was out for work most of the time, but there was no problem with coming & going as needed, and there were plenty of shops etc. around even when working late. Fast wifi and plenty of books to read!
