I stayed at Andreas' place for about six weeks. The place is very cosy. It matches the description. I stayed in the small room - which is small but cosy and the bed was very comfortable. The room also has a desk which was very useful.
Andrea was an absolutely lovely host - friendly and generous. She helped me with tips about the city and she even took care of me when I was sick!
I'd definitely go back and I'd recommend this place to anyone.
