At the beginning of my HolidayI , I was pleased to be able to enjoy Alberto's and Yao's very clean and relaxing feel of the apartment. Being able to walk from their quite neighborhood to the centre of London in 20 minutes was an unexpected bonus and a welcome way to exercise. Both Alberto and Yao, where very courteous and relaxed hosts and because they appear to be at work a lot, I did not see them often ,but when I did they where always up for a brief chat .
