We quickly found the boat as we arrived. It is located in the very centrum of Amsterdam so you walk no longer than 5-20 mins to every sightseeing place. Hans was really nice and helpful. He also lives on the same boat but you don’t get into contact if you don’t want to.
The interior of the boat is no lux at all. If you come there with that in mind you will be happy with your choice. You have a really small kitchen and a small bathroom (the water from the shower gets really hot). The bed is comfortable and big enough for two even if you don’t want to sleep on top of each other.
You should have in mind that it’s a boat. You have to climb down a small straight downwards staircase to get inside. There is no issue with shaking from waves or something. Sometimes you can feel the boat shake but it is really little.
I highly recommend the place for a short trip to Amsterdam.
