I recommend this flat to everyone who looks for a place in Vienna. It's a very safe place, we felt secure, it is very close to train station. Public transportation is easy. It is easy to reach to the center. And also it is easy to walk in order to reach to the center. I can say that flat is better than the pictures, it is cosy, heating system is good because it was very cold outside but we did not get cold in the flat all night. Also hot water is good.
The host - Tatiana was available when we had questions about city/transportation. She replied us quickly when we asked sth to her. For us, it was a good experience to stay in Vienna & in Tatiana's flat.
