Diana's flat was exactly as described, clean and very well equiped. She gave us precise indication to get there from the airport. Also, she very graciously let us stay longer than the check out time since there were no incoming guests. Location couldn't be better, just 10-15 min walking distance from the very city centre, and the neighbourhood was quiet but still full of restaurants, vintage shops, etc. Definitely would reccommend if you would like to make your stay in Vienna unforgetable!
