Due to heavy snowfall we were unable to fly to Vienna. We have been asked repeatedly for a review despite sending an e-mail to say that we were unable to go. The only way that I could say this is by completing the survey which, of course is meaningless. My issue is with the lack of a means of providing this information. We did inform Wendelin at the time. On all other times we have booked with Air bnb we have been delighted with our accomodation
