Very communicative host. Shantia also took some time at check-in to explain the area/transportation and the major sights. He was very kind and helpful, and even takes the time to say goodbye at the end. The apartment is nice, very easy to the city center by train, and in a great location. The only complaint we had was that it was not clear that you have to plug in the washing machine (and we could not find an outlet nearby--we had to use an extender). Otherwise, it was a fantastic experience in Vienna.
