Lovely apartment in a great part of town. 15 minute walk from the central train station, 5 minute walk from the local metro. Loads of food / drink options, grocery stores & bike rental on the doorstep. You can get anywhere in the city within about 30 mins.
Place itself is very clean & stylish. Everything you need in the kitchen (although no microwave), comfy bed, huge TV, good wifi, and great views. Covered, secure storage for bikes in the courtyard.
You do have to climb a lot of stairs to reach the apartment, but on the plus side, if you stay for a week you'll be a lot fitter by the end than at the start!
