We recently spent some nights at Teresa's place with my family, and it has been a very nice experience. Lovely flat, exactly as explained in the website, comfortable, quiet and safe. The neighbourhood is in the south of London, and you will have to use several underground lines to get to the centre, but the price, the apartment and Teresa worth the time, and the connections are good. So highly recommendable, specially if you want to have the feeling of arriving "home" after a long day wandering around the city.
