The place is incredible. Is a modern studio at the backyard of the house. The pictures matches with the place. The transport for going to the "center" of London it's about a 5 minutes walk from the house. You can relax after a long day of visits because the area at night it's very quiet. It's perfect for 2 people.
Sally is an amazing host. It's always ready to help you, and she often reply very quickly. If I visit London again, I would like to stay at Sally's place.
