The room was great! When I arrived Luca showed me around the apartment and explained the various quirks of the place. The room was exactly as in the pictures, the bed was great and plenty of space. Bathroom an toilet were both just as they should be. I didn't get much chance to chat to Luca or his flatmates as I was busy most of the time, but when I did they were all very welcoming and friendly.
If you are after a great value place to stay in a great location in Vienna and you don't mind having different people come and go (the other rooms are also on airbnb) I definitely recommend it!
Cheers Luca for a great stay.
