I have just spent a night at Lucille's place and I can tell you it was my best experience with Airbnb (I have to say that it has always been good so far but not as good as this time). Lucille deserves to be a super host. I knew it would be great (as I always read the comments before booking). She welcomes you with a smile (I was very late at my arrival) and thinks of every little detail. In addition, she has a lovely dog named Chips who would make even non dog lovers melt!
I have found the place I will always go in London if my friends can't have me.
I highly recommend.
