We had a wonderful time staying at Yuri's. He is a lively host and has a great deal of local, non-touristy recommendations to make - be it with food, beer or activities in and around Amsterdam. The house decor is minimalist with all the basic amenities in place. It is located right in the middle of one of the busiest flea markets in Amsterdam with lots of good restaurants, take-away joints available. Central Station area is just a 15 minutes tram ride away.
Definitely recommend staying with Yuri to someone looking for a relaxed, comfortable place to stay at, and not necessarily luxury.
PS: He also provides two bikes to explore the city on its most popular mode of transport.
