It´s a super luxury hotel. It has normal rooms but there are also apartments along the canal. It's like a city since several buildings are joined together to preserve the facades. It is worth seeing, even if it´s just to see the greenhouse hall that is used as the breakfast room. Beautiful indeed. It is part of the Spanish chain NH. They have some nice additional details for the kids and even though it´s a 5-star hotel, it isn´t elitist. It´s my favorite way to stay in Amsterdam. It's expensive, but worth it.
