The SMARTments business "Johann C.L. Hellwig Haus" opened in Berlin Karlshorst in September 2017. The 151 bright and airy apartments in sizes between 22 and 31 square meters are located near the S-Bhf. Karlshorst. This means that the city center is just as easy to reach as BER Airport and Berlin's major train stations. In addition to high-speed Internet and a fully equipped kitchenette, guests can also take advantage of workstations and laundry services.
