Place has some very basic furniture and is far from being cozy like a place you use to live. There's no convenient place for a laptop.
I have had sleeping issue because of hard bed mattress and 100% polyester bed linings. Got cotton ones once requested, but some were dirty, others smelled bad (not fresh). The 2nd bed is also not a good option.
While the building is new and located in 5 min walk distance to U2, things have got loud in night time because of neighbours partying almost every night after 11PM (thought it's forbidden in Germany).
The neighbours are smoking and it gets into the room, so had to keep the windows closed in evening and night time.
