This is the sort of Airbnb you hope you'll stay in, as Airbnb has grown they've let more and more businesses renting rooms on the site. This is Xsjong's home and it's lovely. He was kind enough to spend some time when I arrived giving recommendations of things to see in Amsterdam. He speaks English, Dutch and Mandarin I believe.
The bathroom is gorgeous (he's right to be proud of it), including a hot water shower. The WIFI is excellent too.
It's a 20 minute walk to the nearest metro or there are regular buses from a bus stop nearby. From the metro you can be in Amsterdam Centraal in a few minutes (two stops I think). My recommendation is to rent a bike because if you were to walk to the centre it's an hour but 20-25 minutes by bike.
Recommended.
