Mart's place is great - easily walkable from central station if you don't have too many bags, or get public transport. Mart was a very helpful host - helping me get my bags up the stairs, offering me tips for things to see and do, but also allowing me privacy as needed. I have no complaints and am glad to have seen more of this area of Amsterdam which I loved, rather than always being in the hustle and bustle of the "tourist centre".
