We spent 6 nights in Josef's apartment last week in August. It has everything you would need for a comfortable stay, so close to train station and Metro, 3 supermarkets within 5 min walk, 2 metro stops to the centre of Vienna or just walk if you like walking and exploring. Direct train from the airport will get you there in less than 30 min.
So if you don t care about not having a washing machine or cable TV it will be terrific plave to stay.
Thanks for hosting us Josef!
