My wife and I and another friend stayed at Annette's place for 3 nights. We had a nice stay and Annette was always available to help. We didn't really meet her, but she arranged that we check-in without any hassle.
The apartment was clean and cozy, with all the things we needed. It's not in the city center, but at a nice 20 minutes walk to the train station and city center. Or you can take one of the many buses that pass in the area.
I would recommend this place and would also come again.
