This was our first time with AirBnB, and I have to say that our future accommodations will have to live up to what we have found here.
First of all, everything was like in the pictures. The communication with the host was great, it is close to Wien Mitte, and it is well situated at the first floor in a quiet neighbourhood. Moreover, what I really enjoyed is that our stay convinced us to never choose a hotel since everything that was required for our stay was provided.
It was a fantastic experience, and we warmly recommend to choose Sonja's (and Roman's) place to stay while in Vienna.
