Good connection to the city centre!! Although not the centre of Vienna, you are on the U1 in just a few minutes, which will take you to everywhere in the city centre :) I didn't run into Vasu much, but he was easy to reach through AirBNB-app. He was kind and flexible, I could check-in by myself easily. Room is cozy and Vasu has many brochures available and a nice Vienna map with pictures on the wall (nice detail). I would definetly stay here again.
