This is a gem of a place. If you want peaceful, quiet and lovely surroundings and you are not too fussed about not being in the city center, then this place is for you.
I spent 3 weeks working from Liane's and really thoroughly enjoyed my stay. Compact space, but has all you need. Lots of sunlight, a nice garden view, easy transportation - bus stop is a couple of minutes walk from the apartment and nearest underground is a brisk 12-15minute walk. There are direct, though long (45-60mins), routes to commercial center of London.
Liane is a very good host, communicative and responsive. I would stay again and recommend it to anyone who wants peace and tranquility after a busy day in the city center.
