We had a nice stay at Adeles place, it was very clean and cosy - there were a lot of sweet little things arranged in the flat for feeling really welcomed there :). We could reccomend it 100%. By train you will reach the center in 15 minutes, the train station can be easily reached by bike - there are public bikes just round the corner for renting. By walking you can reach the station in 10 to 15 minutes.
