We had a wonderful weekend on Bob & Eves boat. The room is really nice, the bed comfortable, the host very nice and helpful, and they offered us bikes as well as some beers in the fridge! It was easy to find and is really close to all the spots you want to see in Amsterdam... and it's a wonderful houseboat! Oh, and if you think you'll get seasick: don't worry. you hardly notice that the boat moves, it is a really calm canal, with a boat passing through every now and then. oh, and there is a windmill nearby. In other words: you can't have a better Netherland-feeling, so i highly recommend staying with Bob and Eve!
