It was definitely an amazing travel experience. Benjamin is the most friendly, kind and patient host ever. The flat is so lovely that we would like to recommend it to all who want to have their best trip in central London.
The location is perfect for both tourists and businessmen. It has a bus station just outside the building and a tube station within 3 minutes walking. Furthermore there are many supermarkets and shops around. Not only very close to Kensington Palace, and also you can walk to portobello market on every Saturday.
Here is some recommendation to Chinese.
如果你们有四到五个人，要来伦敦旅行。这里一定是你们的首选。交通便利，位置极佳，商业设施齐全。关键很安全。周末可以走路去诺丁山市集。到伦敦主要的景区几乎只要一趟车，半小时内。旁边就是肯辛顿宫（就是威廉王子夫妇现在住的地方）。肯辛顿花园走过去就是海德公园，天气好的时候可以去骑马哦。
If there would be any chance to come to London again, Benjamin's flat will look as my first choice.
