Bianca's place in Richmond is a wonderful stepping off point for anything around London and the environs surrounding. We stayed for a week in June and everything we needed was easily within 5-10 minutes walk (even three bakeries), anything longer was extremely easy by bus/tube that is 2 minutes (slow walk) to Richmond Station. Best access from Heathrow is Piccadilly (Blue) Line to Hammersmith, then District (Green) Line to Richmond. Maddy is great for local info and loves to help. And she's great fun to talk with.
