We spent 3 night at Rosie's place. We has a lovely, spacious room with wardrobe and a chester of drawers. It can be a bit noisy because of the window facing the street, but it's bearable. Rosie has been welcoming, she let us use all the amenities. The WiFi signal was weak in our room, so sometimes we had to go to the kitchen. The kitchen is not provided with many dishes and kitchen utensils, but there is the essential to have a cup of tea and prepare a quick snack/dinner. It is very close to Old Street tube and Sainsbury. I would definitely recommend it as a base to visit London.
