Daniel's place was just amazing for us to stay. His parents Nik and Karen were amazing hosts and very hospitable. We had stayed there as a family with two kids -7 and 3 years and they were extremely comfortable. They had kept a lot of games there which kept the kids busy. On the first night we reached a little late for check-in but they were extremely gracious in offering us home made food, which by the way was one of the best pasta that I have ever had. Our 3 year old daughter was not keeping well and Karen found us a kids hospital where we could take her in the middle of the night which was a great help in an unknown city as we had to then travel the next day morning. the homemade marmalades were amazing. The 3 nights spent there were very comfortable and enjoyable. The location is amazing as you have a view of the Viennese hills from the house and in summers sit by the pool enjoying the view. The location however is best reachable by a car as it is on a hill. The train station is 5 min walk from there home though while coming back it becomes 10 mins because of the steep ascent. So if you do not have kids and do not mind a bit of a walk, then you could still rely on public transport.
