yours guest - you made a reservation for a small budget room - if you regard the picture of your room category you will recognize it is not a big room ! If you are oversized you should not complain the hotel about your lifestyle ! If you travel abroad you should be able to make a phone call inside europe / austria (usually the most guest buy a prepaid card from european providers). The hotel also tried to give you a call but you did not answer ! If you have not budget to make a phone call abroad you better stay at home (probably it will be cheaper) ! Finally inside your booking it is also signed that parking is not for free. If you have a problem to read your booking details in advance you should not complain afterwards about your own failure. All in all your complain is not convenient !
