This was a fantastic experience. Gaby and her husband, Holm, are natural hosts (with excellent English, in addition to their German) and they have a beautiful apartment near the University and not too far from the Altstadt (Old City). The room and bed are as pictured, modest, but comfortable and quiet. I was there during August when it was hot, and it was cooled down just fine with the breeze from the courtyard. They have a nice terrace-garden that guests can relax in as well.
