I stayed at Judith's house to do an exam in central London and would highly recommend it. Judith is friendly and welcoming and did whatever she could to make me feel at home! The house is easy to find and close to both the centre of London and to Heathrow on the Piccadilly line. It is clean and comfortable and you have exclusive use of the upstairs bathroom and are also welcome to use the kitchen. I got a fab night's sleep and think it was an absolute bargain! Would definitely stay there again.
