I stayed 4 days. At first, location is perfect. 5 minutes by walk from karlsplatz station. It is easy to go anywhere in the city by walk, by subway and by bus. Also easy to get there from airport or wien central station. Eva is very kind. I arrived lately because my flight was delayed but she waited for me until i come. She printed out my photo and framed it so i could feel as if i were in my own home. Room condition is exactly as the photo on airbnb app. Even i feel more wider than i expected. Lastly, i found nice cafes and restaurants around house, you can enjoy them withoud crowd .
