Probably not an ideal location for sightseeing - it's a 25-minute bus ride to Potsdamer Platz and then a 10-minute walk to the Brandenburg Gate and Reichstag Building. But the diverse neighbourhood is quite nice and the apartment is all you could want. Couples may find the double bed too small, but it was fine for this single traveller. No worries with check-in and a good online guide to some local haunts.
