The communication with Markus was not easy. The complete address of the flat was not sent automatically when completing the booking. I sent a message requesting it and got a reply several days later.
We didn’t meet for the check in and getting inside the building was almost impossible. We had to ring at other people’s places until one of them agreed to open the front door of the building. We spent 1h trying to get it and in the meantime we couldn’t reach Markus. It was very disappointing.
On the other hand, the apartment is well equipped, near the supermarket and tram.
