Stefanie's place is really central, in a nice location. Their sun terrace is amazing and the house is quite comfortable, with probably one of the comfiest bed's I've slept on.
It would have been nice if there was wifi though. Also, the apt is at the top floor of a building with 10 flights of stairs (5th floor) - with no elevator. So it may not be the best option if you have large luggages etc.
But overall, I enjoyed my stay.
