This apt is located in a perfect place in Berlin. Very quite and nice square, close to everything. And additionally you have loads of cafes, bars and small shops just next door. You feel safe and comfortable over there.
Apt itself is spacious and well equipped, though lacks one important staff, you can see on it's photos: hairdryer! There were 5 longhaired people and some did not wash their hair for 3 days ;) All other equipment was just everything you need to go for couple of days stay far away from home.
I could see more apts are prepared for tourists, as we could see more people moving in and out, but the house is full of real Berliners, so it's completely un-recommendable for at-home-party lovers.
