We stayed 6 nights in Caroline's house and everything was just perfect: clean house with all the modern confort, very nice typical English decoration, very well located (5 minutes to Bethnal Green underground station, 2 minutes walk to Columbia Road flower market, many restaurants and shops). From there we could easily reach the heart of London (London eye, Covent Garden, Portobello market, Camden, Natural History Museum, ...) using either the underground or the bus.
