Nina's place is fantastic. I stayed two weeks there and was in London for both business and tourist purposes. It is a perfect place for both. Underground and buses are near, so you can get to the touristic places in maximum 30 minutres Supermarket, cafes, restaurants are 5-10 minutes away by foot. Nina was a perfect, very caring host. Even if she was not around, It was super-easy to communicate with her. The house was quiet and perfect for a good rest after a long day in the city. I can only recommend Nina's place and I would like to stay there whenever I'm in London.
