Dominik’s place may be good for students on a very low budget, as it is in some ways similar to a hostel. Don’t expect anything romantic, but it is an upgrade over a hostel if you have a partner because you have your own room. Apart from that, there are multiple guests staying in the flat, so don’t expect to have the entire apartment to yourself.
The building, luckily not the apartment itself, does not smell nice (it smells something like fish). The room was small and very warm (early June), but sufficient for our stay. I wouldn’t want to stay more than a night or two, and I wouldn’t plan on spending any time in the AirBnB itself.
For the cost, there are better valued AirBnB’s in Vienna, but book this if you can’t find others in the price range. It’s a bit far from the inner city (tourist areas), but it is extremely close to a metro (subway/U-Bahn) station. I would plan on getting a public transportation pass if you plan on staying here for tourism.
