Hostels

Stockholm has many hostels, which often are the preferred alternative for families travelling about the country (they are thus far less youth-oriented than hostels on the continent). They generally have a very high standard and are less expensive: www.hostelworld.com/Stockholm

You will have to book your room/bed directly with the hostel. No reservations have been made, so rooms/beds will be available on a "first come, first served" basis. Here are some examples of hostels in Stockholm city:
