We (me, my husband and our little daughter) have been on Derk’s boat for a few days. You can find all you need close to the house boat. Bakery, super market, restaurants, Metro station - everything is just a few steps away.
The boat has almost everything you need for a stay. And if there is anything missed, just give a call to Derk and he will bring the missing item immediately. That brings me to the host.
Never met such a friendly and helpful landlord. We had a personal issue during our stay and he supported us to overcome the problem. I really recommend the boat for a stay in Amsterdam.
