The apartment is really small. True, 5 people can sleep in it but don't expect anything else. We had no room for our stuff, couldn't use more then 2 computers and almost no place to eat.
Now the really bad stuff:
The forks, plates, spoons etc.. were really dirty. I mean, we couldn't really cleaned them. There's small place to cook.
As for the good side: the place is about 20-30mins walk from the city center.
We lost a 100€ deposit because we forgot to move the table back (we had to move it 1,5m away just so we have some place in the livingroom/kitchen).
I honestly don't know what you should get for this price as Vienna is more expensive then some of the places i've been before but i highly recommend gettibg another place then this.
