This is the first visit to UK and it was fabulous experience! Especially the host, Adam, was very kind and his house was very clean! everywhere in his house, there was small memo explaining how to use in each facilities.
The tube station is near from the house as well (6~7 min by walk). It's around 30 min distance from airport and center of the London as well.
I recommend you to use this place if you are single or couple visitor!
