We really did enjoy our stay in london at Janes home (2 adults 2 childs).
She is a lovely person and a good host.
Her house is homely, the surroundings are opportunly (market, restaurant, transport connection, ...).
The best connection from LHR is Picadilly to Hammersmith and then 266, and about 1 minute walk.
If we come back to london, we will join her again.
