We stayed 4 weeks and our experience was excellent! The apartment was very clean, stylish and comfortable. It also has everything you would need for a long stay in Vienna.
The location is a bit far from the center, but very well connected with public transport, so you can get there in 15-20min.
Communication with Theresa was great and with fast responses, and she even left us some gifts from Vienna when we got there.
Overall an excellent Airbnb, we would return with no hesitation.
