We had a great stay at Diana's place. While we unfortunately didn't have the chance to meet Diana in person, her and her helpers made sure that everything went as smoothly as possible. She was extremely accommodating with our specific needs and flexible with our arrival/departure times. The apartment itself is also nice; I was surprised at how big the living area was considering its great location. The apartment is very very well-located close to several tube and train stations, also not far to walk closer in to see the main tourist sights. As mentioned in the description, the bed is perfect for two, and then the camp-bed and comfy couch make it very easy for four adults to fit comfortably. Thanks again to Diana!
PS: We'd definitely recommend Fork Deli Patisserie across the road for the best coffee!
