Kathy was very warm and flexible. She went out of her way to meet us a second time as we were running late on the first night. She was kind enough to recommend a few sights, restaurants, etc as well.
The apartment is cozy, well-kept and spacious enough to fit a family of five. The kitchen was very well-stocked with tons of food and all the necessary utensils.
Location-wise, the apartment is close enough to central London, and only a short walk away from the Portobello market.
