There are 85 steps up to the apartment so be prepared! The location is brilliant! We walked to city centre a lot of days but we got the U-Bahn too which was really close by (U1, U2 and U3). There were also a number of buses from outside the door which could take you all around the city. 5 of us stayed in the apartment but we could have fitted twice as many in the space if there were more of us (3 big bedrooms plus sofa beds)! Our biggest fault is the mattress quality. They had very little support for the back and we were in quite a bit of pain from that. We thought we might have had return home early when one of us couldn't walk after a few days. All in all a pretty good place but not perfect
