All in all the stay at Stephans place was nice. The location is in cozy Neukölln, and the street is quiet and only a couple of blocks away from the center of Neukölln.
We didn’t spent that much time at the place, but it did the job for us, though some things weren’t optimal.
The bed is pretty bad and the duvets are poor. The house is in the backyard of a large apartment complex, which means that every time someone comes home and enters the yard, all automatic lights are lit outside - this is problematic when the house doesn’t have sufficient curtains. The bed is right next to the fridge which is pretty noisy. If you have trouble falling asleep, bring a sleeping mask and earplugs.
Also it says that there should be toilet paper, soap etc. We were staying for 4 nights, and there was one role of toilet paper for two people. Also there was no more hand soap in the kitchen and no shower gel as promised.
