Stephan's place was in a perfect location. It was 3 min walk from old town square and and walkable distance from all major attractions.its just a few min from the train station. The apartment​ was maintained very well and was clean and spacious. It had everything we needed for our stay. We will definitely recommend it to others.
One area which needs to be better is initial communication about how to reach the apartment and check in instructions which will make check in a lot easier,as we had a hard time reaching the apartment and weren't sure how to get in.we just guessed and buzzed the apartment and the housekeeper lady Hyla was able to let us in.
For those coming from central station we took the ubahn to museum and then changed to green line and got down at old town square.
Overall an excellent stay and will definitely be back .
