Nice place to stay, the area is really nice. Though, the apartment is located at a very busy road and the apartment isn't very soundproofed. So if you are a light sleeper, prepare to wake up early due to the traffic. Also, it seems like the walls are very thin, so you can't really make that much sound yourself. The rules clearly state to not have a party or invite people. A note in the apartment also tells you to lower your voice after 8pm which seems a bit much to ask really. Also the bathroom could use an upgrade, the shower isn't really suited for people taller than 1,50m. But, all together a nice place to stay, the kitchen is nice, you can make your own food there easily and all the utilities are there. Nice location in Kreuzberg with a lot of nice spots close by.
