Don't expect too much in terms of comfort (the house, like most similar English residential buildings, is hardly insulated, so it can be rather hot or noisy, none of which is the host's fault), but it's perfectly clean, perfectly functional, within easy walking distance of two Tube stations, and at a price for which you'll be hard pressed to find anything at all in London, so if you're traveling on a bit of a budget, I can whole-heartedly recommend this!
