Really enjoy to stay there. John is a friendly, nice gentleman and will not disturb you during your stay but certainly can contact him when it needs. A cozy flat with good location just ten minutes walk from tube and easy access to city center with lot of buses. No need to change the tube to Heathrow. It will help a lot if you have heavy luggage. Lot of small shops around and the big supermarket just 10 minutes walk. I definitely will recommend the flat.
