Can't really remember how I came across this site, but it is cool. Three 'hotels' in the Dutch city of Harlingen: one in a crane, one in the lighthouse and one in a boat. All beautifully designed. This one is the crane (Havenkraan), which guests can turn 360 degrees while staying there. The cabin is failry small, but the large window and the possibility to turn around offers an amazing view which hugely compensates for the small space!
