The club has no official hotel collaborations, so it's recommended to book your stay well in advance and to use different price comparison sites (Trivago.com etc) to find available rooms. Recommended areas are SÖdermalm, Gamla Stan or near the Central station. Several Scandic Hotels in Stockholm have cabins (small rooms without a window) which can be quite affordable.
