I had a great stay at Nienke's house; it's a lovely room (with a massive bed!) on the top floor, with a spacious private bathroom and a little breakfast room. It's close to the NDSM ferry and there's a supermarket nearby for the essentials. Nienke and her family were very welcoming and friendly, and I liked the feeling of staying in a real home rather than a commercial vacation rental. My top tip would be hire a bike - the house is about a 15 minute walk to the ferry, or a 5 minute bike ride, plus it makes getting about the city much faster!
