In a former music studio where the Beatles recorded, Generator is a design-led hostel run with German efficiency. It features a 24-hour lounge and cafe, single and double rooms and 6- and 8-bed bunks, all with in-suite bathrooms with additional showers down the halls. With 161 rooms, it is Hamburg's largest hostel, new in 2012 and next to the central train station In the gayborhood in St. Georg.
