I had a great stay at Sacha's place. The house was very clean and beautifully decorated + Sacha and Mark were fantastic hosts. Among my best experiences with Airbnb.
I also got to enjoy the lively East end for the first time in many London trips. I wish I stayed for longer.
I hope to go back if I get a chance and in the meantime strongly recommend Sacha's room to other travelers staying in London.
