William was a great host, very friendly and helpful. He was very responsive to messages if there was any question you have. The flat was fantastic, easy to check-in, cosy and had everything as described. The kitchen was impressive, with all the equipments and ingredients you need for cooking. And there were so many amazing games and books in the living room. I would definitely recommend this flat, especially to travelers with kids. The flat also had a great location. It only took a short walk to the major tourist attractions.
