Sylwia is defenetely a good host, but the accomodation is nothing special, it is located in an unpleasent building and inside is quite dirty (the ceiling of the toilette is fully covered by mold). The sad reality is that you cannot pretend something better at the same price in a such pretty good position of London, so unless you don't want to invest more money you will not find a better solution.. but still I wouldn't reccomend it
