The apartment was clean, big and close to the city centre. There is big supermarket nearby and you can walk to the central station by foot. Basic ingredients are given and the kitchen is well equipped, for example with a microwave, an oven and a coffee machine.
Unfortunately, we had to wait a bit for our check-in, but when Christian arrived, he was very friendly and showed us the apartment in detail.
There was some trouble with the WiFi, but we contacted Christian and he came to repair it the next day.
