Matthijs is a fantastic host and the houseboat was a great stay.
I would note a few things.
The boat has extremely little to no motion, if that would be a concern to some.
The bed is very comfortable-I slept extremely good. I do wear earplugs, which would help with the occasional siren and church bells.
The tram is right up the street-you can explore the entire city either walking or using that station as a start/end point.
Sterks is right on the corner-can get pretty much anything you would need.
I would highly recommend this host and his awesome boat, for your stay in Amsterdam.
