Sonja's place was excellent! The entire place seems to be have been recently renovated and it was done well. Bathrooms, bedroom, and shared kitchen were modern and clean. The area that the airbnb is in is conveniently located next to Wien Mitte station, which connects to virtually every single mode of public transport (U-Bahn, S-Bahn, Bus, etc.). The only issue I had was that the bed was too comfortable and the neighborhood too peaceful that I had trouble getting out of bed :) I would definitely stay here again.
