Really good location, within walking distance of the main sights & close to Friedrichstraße Station, giving you links to the wider area, including the zoo, which was really cool (especially the pandas :)! We got the train back to the airport very easily from there too.
Close by eateries included currywurst, Woop Woop liquid nitrogen ice-cream & a donut stall next door.
Apartment had everything we needed - could have done with better pillows, but the bed was really comfy.
