We were at the apartment around 9 o‘clock because we used a night train and were greeted very unfriendly that we are too early, although we texted a few days before that we would arrive early and would like to leave our luggage, but as an answer to that text, we just got an answer that sounded like a automatic answer. And we didn’t know where to ring, because the house name were never mentioned anywhere (also not in the link he sent me after the call AGAIN and was sure it was there, where you have to fill in your information) and when we called the number from the profile, he was just unfriendly and didn’t let me finish speaking.
If you use the normal check-in time you maybe have a easier way of getting in, but that was just rude to us.
