Örlogshemmet is found at Teatergatan 3. A small street right between the Grand Hotel and Radisson/Strand Hotel. A quiet street a bit on the side of the busy city area yet in the middle of town.
No. 3 is also the home of one of Stockholms/Swedens most popular nightclubs, Wallmans Salonger. 50 meters down the street you find ferries that can take you on a daycruise around the beautiful archipelago or just across the bay to Djurgården.
The Royal Dramatic Theatre and the Opera are both just around the corner. A 5 min stroll will take you to the Old Town and the Royal Castle.
