This is a very nice comfortable flat. We found it very peaceful and quiet. It is nicely decorated. Very easy to find, it is only 10 minutes from the M1 and a 20 minute tube ride into central London. The hosts provide comprehensive info on the heating, the wifi etc and they answered all emails quickly, providing extensive and informative replies. They were also quite relaxed and flexible about check-in/check-out times which is a definite plus point in my book.
I would definitely stay here again.
