It was a nice apartment, in a good location, very warm for freezing February. Good Instructions on how to get into the apartment. My only problem was with the non existing Host, in real terms. I did not get any real help (e.g. with a luggage problem etc). Just irritating seemingly polite mails of the type "if you need anything don't hesitate to ask".
When booking for Vienna take into account a 3,5€ per person per day charge (something that i was notified a day before getting into the apartment). I did not like leaving the money on the table with no proof that someone collected it (no receipt?).
I also found the charge of 100€ too much for a one time apartment cleaning (i only stayed for 4 nights).
If you sum up all these extra charges, the advertised price nearly doubles.
My communication with the Host i never saw, was problematic all through my stay. Last straw was the mail with instructions on where to leave the keys, two hours after i left the place.
