This is a beautiful building in a beautiful and central part of Stockholm. But be aware that it is a hostel, not a hotel. Rooms do not have their own bathroom and you are expected to make and strip your own bed. There are, however, more opportunities to meet fellow travelers, a kitchen to cook and socialize in, a pool table in the common room, and (and this is key in Sweden) laundry facilities in a country that doesn't really have laundromats.
