I stayed on "Zicht" for five days with two friends of mine. It was a real "living on a boat" experience, as we had wanted it. The description is accurate - the place is really small and the ceilings are low, but we managed alright. The beds downstairs, especially the one on the right hand side, are actually bigger and longer than they look. I am tall (180 cm, but had no problem sleeping there). The toilet's ceiling is really low - too low to stand straight, even if you are not so tall. I wasn't prepared for that, but it was alright. The location of the boat is really central and ideal to explore the city. It is not in a quiet Gracht, but on the Amstel river, so in an area which is a bit busy. At night it was quiet though. The place is ideal for two adults, but we also managed in three quite well, organising the space as well as we could. For us, it was something really special to stay on the boat and we are happy we decided to do it.
