I stayed 3 nights at Xiong's flat and had a great experience. Xiong is a very nice host, always helpful and trustworthy, he made everything to make me feel comfortable - and indeed I immediately felt like at home - and even gave me some advices on places to visit. The flat is very clean and calm and in a safe neighboorhood - in addition of being a quite spacious flat. Next time I'm back in Amsterdam I will for sure try to go back to this place, and of course I strongly recommend Xiong's place for anyone looking to have a great stay in Amsterdam.
