My boyfriend and I stayed in Susan's guest room for one night for a flight out of Heathrow the next morning. Susan and her family are very nice. She is also very knowledgeable about the bus routes around her area.
She was very flexible and accommodating with us when we arrived much later than first expected.
The room was clean and comfortable.
If you are coming from or going to downtown London, it is a bit of a mission. It was very convenient to take a taxi to the airport the next morning from her place, but the bus would have been quite a bit longer.
