Our two night stay at Sonja's place was quite awesome - great location with everything in walking/cycling distance while not being too close to the touristy spots in Amsterdam.
She is a great host, putting a lot of effort into making you feel comfortable - fresh bread, lovely seasonal flowers, fruit and a bottle of bubbly.
The boat itself is stunning and it was great hearing how much effort they had to put in to get it.
I can highly recommend this place.
