Well, I have now been staying in a fair amount of Airbnbs and I can safely say that my experience at Robert's house has been once of the best.
The apartment is stunning with tasty decoration (including some gorgeous paintings made by him), great/modern equipment and a very conveniently location in a quite and green area with easy access to everything.
Robert is an exceptional host, very kind and eager to make sure you are comfortable. No hesitation here, one of the best place to stay in London!
And if you're lucky, you might even be treated to a slice of Robert's unforgettable chocolate cake.
