The apartment is located on the ground floor but as windows are well insulated, you don't hear any street noise.
The apartment was very clean, and had every amenity we needed. I think it is 100% for rent and everything was very pro. We found the place perfect for a 5 days visit to Vienna. Tram and U-bahn is within walking distance so it is very easy to get to the city.
Will most likely stay here again next time in Vienna.
