It was a great experience. The appartment has everything we needed for spending a few days in Vienne. The communication was great and really helpful from before arrival until the departure time. It was even possible to leave our luggage after the check-out time since next quest arrival was later. He gently provided information about transportation and main attractions, giving directions and suggestions. There are around five steps to reach the elevator (which was not a problem for us). The sofa-bed (on the second bedroom) could be a little more confortable. The appartment is really large and confortable for 4 adults. We would definitely look for staying at Ferdinands appartment again in a next visit.
