I can't even say enough good things about Christian's AirBNB. Before we booked I was looking through the photos and as soon as I saw that he has toys for kids, I booked. We stayed with our two young kids (3 years and 6 months). There was a pack and play with an attached changing table provided and even a small baby comforter. There was a high chair and as I mentioned, matchbox cars, animals, tractors, and kids books. The place was immaculately clean and only a 2-3 minute walk to the train station. It was also very affordable which we appreciated because traveling with kids is already not cheap. It was perfect in every possible way. Christian was also extremely kind and very fast to respond to messages. He also made every effort to help us find a way to enjoy our last morning in Vienna without having to haul our suitcases around. I highly recommend staying here. The apartment also has a really good view which is a great bonus!
