Stayed here for 3 nights and would highly recommend it to other travelers. It's secluded but very quick access to central station so doesn't take long to get anywhere. The little road down to house is full of lovely little houses and there a lovely bar/care at corner. There is lots to do in the North also and for one day we used the bikes from Karina's house to explore Noorderpark, Windmill D'Admiraal, NDSM and found some excellent places to eat like Plekk.
The bed is extremely comfortable and the place is very quite so nice to have proper lie instead and rest when at the boat house.
Getting into central station is very quick and easy...about a 5 minutes walk and you never have to wait long to get across the water.
This was my 5th time to Amsterdam and I would definitely stay here again when I return to the city.
