Hotel am Bahnhof

I booked a list minute stay for 2 nights in this hotel. Distance to the Feldkirch train station is ideal. Check in was very fast and easy. The weird thing were the signs on each of the hotel doors: Do not disturb / Do not knock! Even weirder was that at 4:00 in the morning someone knocked on my door several times, then tried to open the door. Thank god it was locked. This guy walked up and down the hall and tried every door, repeatedly knocking until 4:15. When I called the hotel owner, she said "It's probably just a drunk guy. I am not at the hotel, so there is nothing I can do" and hung up again. I feel it is the hotel owner's responsibility to have a solution or to be available to provide a solution, ESPECIALLY in cases like this. Instead I had a very bad night of sleep, and made damn sure my door was locked during the 2nd night as well.
