We had a wonderful time at Gert and Nienke's house. We only stayed 2 nights but we were happy to have our own little space on the 3rd floor of this charming, well decorated, confortable and welcoming home. The breakfast made us feel like our own private high end room service. NDSM is a perfect spot to discover Amsterdam, easy to get there with the free ferry that runs every 15 min. We recommend it without hesitation. Thanks again!
