We had a great experience at Nima's place. Pre-arrival communication was efficient, and Nima gave us a house tour when we reached his home. The walk + ferry into the city takes about half an hour but is completely free and became an enjoyable start/finish to our days - Amsterdam Noord is also a cool area in itself and we wouldn't have experienced it had we not stayed here. Though we didn't spend much time with Nima, I would gladly recommend his place to anyone visiting Amsterdam.
