My stay in Sabine´s appartment was great. I was there for IFA, so had to commute to the Berlin fair grounds.
Check-in worked flawlessly. The place is very clean and has everything. The best part was the location. It´s in a quiet street with a number of stores and good restaurants. And it´s a short stroll away from 3 key public transportation stops for subway and train.
I can highly recommend.
