The houseboat will satisfy the solo or couple traveler to Amsterdam. I was met at the houseboat by the host after she gave me excellent instructions prior arriving.
Check-in couldn't have been easier; she even took time to have me practice unlocking the front door which can be tricky, especially if you've had a few drinks :)
I enjoyed every amenity on the houseboat: there's tea, coffee, many appliances, a very nice shower, and a comfortable bed.
I would book again without hesitation on a return trip to Amsterdam.
