Very easy check in and out. Good location in Kreuzberg near to good local bars, restaurants and U-Bahn stations. Very clean and tidy space with lots of amenities. Front window has a shutter which completely blocks out light which is very useful if you come back from a night out and need a good sleep during the day.
Only significant drawback was we found the flat a little chilly (it was February) as the heater in the front room does a decent job in there but the back room and sleeping area was significantly colder.
