The apartment is quite near the central station but getting there is a bit tricky. We eventually took Uber and the rates were rather reasonable, even all the way to Schiphol airport Uber was around $40 so with the three of us, it’s only a few more Euros than the bus/train combo.
There aren’t a whole lot to do within walking distance but the bus stops are only a two-minute walk away. You need to be aware that there are two bus companies, GVB and I’m not sure the name of the other one, and their tickets are different. The 391 and 394 go straight to the Central Station and you can pay for each ride (2.80 euros) with credit cards on the bus. Or you can get GVB day passes but then you have to do a metro/bus combo to the Central station. The latter sounds complicated but it is super easy.
We tried the restaurant IJver at NDSM and it was excellent. It’s about a 25-minute walk. There’s another restaurant that’s very close by but we didn’t get the chance to try it cuz it only opens from noon
