Amazing host : Sheiraz welcomed us at the underground station, recommended us things to do in London, and was all the time very concerned about us having a pleasant stay. You can also have some privacy because he is most of the time out.
The apartment has all you are looking for : near transports, clean, quiet, comfortable bed, clean bathroom.
My girlfriend and I definitely recommend staying at this airbnb if you are looking for a top price/quality ratio.
