My family and me (4 adults) spent a long weekend in Amsterdam and felt perfectly happy at Jan's houseboat. Everything was great: the communication was nice and helpful, already before we arrived. There was everything we needed, from dishes to towels, and much more space than expected for a houseboat :D Breakfast on the terrace, dinner in the kitchen, relaxing on the couch...all possible. It was very clean and very cozy, we felt absolutely comfortable. Jan lend us four bikes which was great for riding to the city centre (approx. 20 min), but there are also public transport stations nearby. The atmosphere around the boat was nice and quiet. We'd love to come back some day :)
