Certainly enjoyed my short stay with Yasmina and Andrea. They both were great hosts and very helpful in explaining the lay of the land.
Lots of bars, restaurants and shops nearby.
I especially liked the bath and kitchen I got to cook a bit while there.
If you are arriving via LHR it takes 1.5 hours by train/tube. Travel using HeathrowExpress will take half that.
Yasmina's place is about an 8-10 minute walk from the Tube station.
