Although we did not manage to meet Diewert in person, he was very accommodating from inquiries to booking, arriving and upon leaving he is always quick to responds which enhanced our stay in his cosy and clean houseboat! Clean bathroom, good supply of the basics including hair dryer, location is perfect, quiet and secure neighborhood, and also a reasonable bike hire. Thank you for the lovely experience in your houseboat! The only downside is the tiny window in the bathroom without any curtain/blinds ~ I would definitely come and stay in your houseboat again if im going to Amsterdam in Spring! Hopefully to see you by then!
