We stayed in George's place during 2016 Christmas. It's very cosy and tidy. Well-equipped kitchen, clean and new-looking bathroom, high-speed wifi... everything made a great stay there. And public transportation is very convenient in London. There are bus stops downstairs. Though it takes about half hour to go to the city center, but it's really convenient. And local and International supermarkets are just nearby. So we've never worried about buying food or other stuff even during Christmas holiday. Though it's not so close to the most popular scenic spots in London, George recommended us some outlets in Hackney, just several-minutes' walk away. Besides, George is a nice host. He sent us an list of the stores, bars and some other stores nearby. It helped a lot.
It was a lovely place. We really enjoyed our stay there.
