Staying at christophs place was amazing. He went above and beyond to accommodate our needs and was a pleasure to be around. He even made us a classic Austrian barbecue which was delicious. The location is perfect as your are close to the center of Vienna as well as the river. Not to mention you are right by a train station which can take you anywhere. If I ever visit Vienna again I will be sure to stay at his place again and I highly recommend it to anyone looking!
