Staying at Susan's place was a very good experience for me. Her home is close to two different bus stops that take you to two different train stations. This enables you to get into London easily.
Heathrow is a 40 minute taxi ride.
Her place is very clean. The room included a very nice shower, where the water is always warm/hot. The toilet is right down the hall.
Susan respected my privacy, but at the same time it was easy contacting her if there was a need.
I highly recommend her place for anyone who needs a place to stay while in London.
