I stayed at Alison's house for 3 nights and even though I didn't see much of her everything was well thought of, from my somewhat late arrival all the way through my departure. The place is warm and clean, and very close to the tube station, and it takes just under 30 minutes to get to central London which is very convinient. Heathrow Connect station is a short tube ride away and it makes getting the the airport very easy. Overall, I'd recommend Alison's place to other travelers.
