We had a great stay at the Appartment! Everything was very tidy, clean and in complete accordance with the descriptions on the website.
The location of the appartment was perfect for us, because everything in the center is basicly within walking distance. However, since we weren't so lucky regarding the weather, we also took the subway and the tram, which was also no problem because all the stations are very close. The shuttle-bus from the airport arrives at the Morzinplatz within 20 Minutes, which is very close to the appartment, too.
Moreover, there a two Billa-Supermarkets as well as a couple of restaurants nearby.
Dan was really uncomplicated and attentive. He answered the few questions I had at short notice and was concerned that we had a pleasant stay. Since everything was so well prepared, we didn't really have to ask for anything anyways.
Finally, in the light of the above, I found the price to be very reasonable and would definetly recommend Dan's appartment.
