Stop looking and stay here. You're going to Amsterdam, so make like the Dutch and sleep on a boat. A bedroom tucked into the bow of a boat sounds cramped and uncomfortable—but Sonja's guest room on the Tasmania was entirely the opposite. With skylights and portholes and plenty of room for your bags, the room was great.
Sonja was also a great host. We booked three nights, but a conflict came up for the first. Sonja was having a summer solstice party and was worried we wouldn't be able to sleep for the noise. She ended up offering to put us up in a hotel for that night and extended an invitation to the party. That's way more than we had any right to expect.
