Patrick is a wonderful host. The flat is exactly as it appears in the photos (or even better), and is placed in Mitte, plenty of bars and restaurants, only 10 minutes walking from Alexander Platz and with a tube station at the door.
At the arrival Patrick provides you with tips for both the house (wifi password, etc.) and for the neighbourhood (supermarkets, etc.).
Absolutely recommendable. I will repite for sure in the future.
