If you're staying for a longer period of time, or moving for work - Stay Away.
As a part of relocation process to Austria, you'll need a "Meldezettel", essentially an address registration. Without this piece of paper you won't be able to get anything done. Opening a bank account? Getting a Phone Number? Work Permit? - Forget about it. When I asked the host to sign this paper for me, she refused. She told me she didn't have to sign this by law, and wasn't going to. The host was very uncooperative, and you'll probably end up in a similar boat very soon.
I know for a fact that this generally isn't an issue with most other AirBnb rentals, as I had a different host sign a Meldezettel for me before, as did all of my colleagues who moved from abroad.
The apartment itself was very nice, and the kitchen was very well equipped, apart from a few very common items missing. There wasn't a Chef's knife, a strainer, etc. If you're planning on cooking your own meals, you might have to get those yourself.
All in all, if you're coming as a tourist the apartment might be a good choice. Otherwise, you should seriously think twice before renting an apartment from this host. Don't make the same mistake I did.
