Daniil is a great host: very responsive, friendly, helpful and trustworthy. He helped us from the moment we landed on Vienna till the moment we left for the airport for our trip back home. The house is very cozy, modern, enjoyable, clean and comfortable. It includes anything you might need. The U-bahn line is just in front of the house and you can even easily walk to various places around Vienna. We slept very comfortably as a 4-person group. I highly reccommend that you stay at Danny's place when you visit Vienna.
