The apartment is exactly as on the pictures, lovely and clean. The location is ideal! Luigis mother was very kind and gave us brilliant tips on what to see and where to eat! You should however know 3 things:
1. The apt is badly suitable for tall men (over 190cm): the ceiling on the mezzanine is only 190cm high (Luigi informed us about this) and the fixed shower head is about 180 cm.
2. The stairs leading to the mezzanine are somewhat insecure, I even fell once despite being very careful.
3. It is almost impossible to sleep with open windows, the street is extremely loud (and I am not particularly sensitive, I live in one of the loudest streets of Berlin).
If you don't mind these 3 points, this is a great place to stay at.
