It's very good apartment that situated near Nordbahnhof s-bahn and u-bahn station. Two big rooms and four sleeping places are ideal for 3 or 4 people. Good flat for a good price! It's just 5 min by foot to Oranienburger str., 10 min to Unter-den-Linden or less. Javier and Rubin are very friendly. Thank you for unbelievable stay in Berlin!
