My friend and I had a lovely stay at Rebecca's flat. It is about a 7-8 minutes walk to the overground station West Brompton and the underground Earl's Court station (back entrance) on the Picadilly (very convenient for Heathrow airport access) & District line. There were many food options available in Earl's Court and a large Sainsbury (supermarket store) 15 minutes away.
Two stations away from a large shopping center at Shepherd's Bush. Other locations easily accessible via the Picadilly line. Rebecca and Michael were very helpful with any issues we had.
