We had trouble finding accommodations in Amsterdam for six days, even for just our first night. It turned out it was the beginning of the King's Day celebrations, so we felt lucky when Expedia provided us with Zoku. The place is very hip, has a great rooftop garden/bar/restaurant, and features well-designed rooms with super-comfortable loft beds and kitchenettes. The downside was that the room was quite expensive; we paid about $400 a night with no breakfast (or parking) included. In addition, the AC/heating wasn't very efficient. Were the weather much warmer, it would have been uncomfortable, especially at night.
