We stayed at Hester's place on our short visit to London for a festival. The festival was at Wembley. This location worked really well, because it was a 20 minute train ride to Wembley stadium. It is also about 20 minutes from the centre of London and the shopping areas.
The positives were :
Hester is a great host
Comfy bed
Nice kitchen
Cute cat
Nice interior
Close to tube
Close to grocery store
Close to Wembley
