Great hostel. Located in a residential area but you can easily walk to a bus/tram station (like 5 min) or walk to Alexandraplatz (15 min) or to the East Side Gallery (15 min). It was clean and the staff were always helpful. I checked in late (like 11 pm), and I thought it was going to be a hassle to check-in, but it wasn't. Except for the fact that Singer109 is not really in Singerstrasse and late at night was a little worrisome not finding it immediately. It is like on the next street where the entrance of many residential homes/apartments are. But overall, would recommend.
