The apartment of Alexander is exactly as described and it's one of the cleanest I've ever been to! Every single corner is spotless!
The bed is comfortable and the wifi is excellent, I had to work from there and the desk+internet were perfect for me different meetings!
The U-bahn is also a couple of minutes by walk and the bus is right in front of the building
The minus is that you can hear the Ubahn (but wasn't too loud) and the neighbours might be a bit loud sometimes, but as a fairly light sleeper, it wasn't that much of a problem.
