Kiong is a very nice person, he helped us very much during our jorney and it has been very helpful and kind.
The house is located in a very nice and quiet residential area a little bit far from the Central station of Amsterdam (you take about 15-20 minutes by bus, but is very easy to reach).The apartment is very clean and pretty with a big bathroom and a very comfortable bed. Also the duble badroom is very big and Xiong left us a lot of space for our clothes in his wardrobe.
Ps. for girls, bring an hair dryer with you if you think you will probably need it because Xiong hasn't it.
