I had a great time at Lynn's place. The location is - as correctly described - really central and the room was very clean and nice. Also, as it was part of a four-room flat, where all rooms were rented to AirBNB visitors, you could meet fun people every day, which I enjoyed most. We didn't meet Lynn, but the key instructions are so precise, that there was no necessity to. Will go there again on my next trip to London.
