Ana is a great, respectful and kind host, and the house has a perfect location.
Ana was like a angel in my travel. She helped me adapt to the City and made me feel at home. She even changed her routine to greet me the day I arrived in London. And you can learn/practice Spanish.
In addition, the house is 20 minutes from downtown by bus (cheaper and tourist subway) ..
For all this and more, I recommend fully Ana's house to visit London
