I stayed at Qisheng and Yijing's house for a month. The experience have been unique! Starting from the area: it is a quiet living and well served area ideal for who wants to avoid fast-paced central London. All you need just close to the house(1min supermarket, 1min bus stop, 5min over ground and 10min underground stations). The house itself is entirely new and my room was quite large for London standards and had all comforts(wide private bathroom and weekly cleaner). They have been the best hosts I've ever had: really kind and down to earth people always available for a good chat and for giving me suggestions about what to visit in the city. Highly recommended!!
