Everything was nice and clean, the apartment is very cozy with a beautiful natural lighting. The location is great, quiet place, you can get everywhere using the metro (you can't get lost using Vienna's public transport) and if you're used to walk, you can ever get to the center by walking, no big deal. There's a supermarket near the apartment, which is super useful if you want to buy some food to make your stay easier (and cheaper). To sum up, as good as you can see in the pictures!
