Built in 1924, this was once the world's largest yatch, but has been converted into a floating hotel. We thought this was a very unique experience and we enjoyed our stay very much. The cabin was cozy and comfortable. Extremely convenient to Stockholm's Old City (Gamla Stan). Easy walk to the Royal Palace, Stockholm Cathedral, the Swedish Parliment, Stockholm City Hall, Central Station, and many other sights, shops, restaurants, places of interest and public transit. The buffet breakfast was outstanding. I would highly recommend staying onboard when in Stockholm. Only 2 minor negatives: 1.) The property description says laundry facilites are available. This gave me the impression they had washers and dryers onboard for guest use. They do not. Only an off-ship laundry pickup service which is expensive in Stockholm. One of our priorities in choosing a hotel is the availability of self-laundry service. I'm glad we stayed here, but I likely would have chosen differently if I correctly understood the laundry service situation. The owners should update/clarify that properly in the Property Description. 2.) The bathroom door in our cabin (217) is VERY squeaky; needs lubricating.
