In the positives: comfortable apartment, great location, clean, great communication with the landlord.
On the negatives: no linen or pillows for the couch, so my friends had to use towels to sleep on it and the wooden support under the couch was broken which made it risky for two people to sleep on it.
Other than that, we had a great stay, because the apartment was overall comfortable and clean. So, I would recommmend it. Thank you again Sonja!
