Roxana's place was a comfortable studio apartment, and had everything we needed for a 3-night stay. It is right next to a tram going into the city (about 10 minutes), and is 15 minutes walk from Vienna hbf (or a 10 minute bus) - we would suggest getting the WienMobil app for the public transport. We did not notice much noise from the street, despite the windows facing the street. There was a bit of noise during the night from near the bathroom (maybe hot water or air conditioning?), but closing the doors between the living room and the entrance blocked out any of noise. We would happily stay here again!
