The apartment is ideally located : it is easy to go everywhere on foot or by bike.
On the bad side, some kitchen ustensils were not clean (e.g. baking sheet, pan), and the bedroom is bright in the morning (the curtains are almost transparent) and a bit noisy in the evening (I guess it's totally ok if you sleep easily).
We always had good communication with Gretel.
The café downstairs makes delicious coffee.
