We had a mixed experience on the houseboat because of an issue with the marina where it was moored (an electrical connection to the boat was burnt out and caused power and plumbing issues in the boat). But the host was excellent at communicating with us through the event and sent someone to repair it ASAP. In the end, we cut our visit short but it was through no fault of the host.
The boat itself was pleasant, located near good restaurants and markets. The ferry to the central station is free and easy to access. The boat itself is right near the gate to the marina so so don’t have to walk forever. The marina center (just a short 2 min walk) has laundry and shower facilities which makes it nice if you’ve got multiple people wanting to get ready at once.
I wasn’t expecting the house it to be so tiny (when sitting on the toilet, your knees almost touch the wall) but I probably should’ve known that. Anyone who is older/bigger/heavier might have a hard time just getting around the boat.
