Great location - close to the Altstadt as well as public transport. We walked to the river every day and sat to enjoy the scenery. Plenty of nice bakeries and restaurants nearby (within 5 minutes walk).
The kitchen was well furnished. Plenty of extra pillows and blankets available if needed too! Hatice provided two umbrellas for use if needed as well as some food & beer to welcome us when we arrived.
The only negative I had is that my mother was unhappy a few nights since the people upstairs were rather loud - I believe they were watching movies. This wouldn't be a real issue except that the noise would continue until around midnight, sometimes later. After I gave her my white-noise machine, she had no problems. Otherwise we had no complaints and wouldn't hesitate to rent again!
