Hi Benedict,
We stayed at this lovely apartment with or son of 13 for three nights as we explored Vienna. The apartment is wonderful and very clean.
Everything is just close by the apartment like; U bann, mini supermarket, pub's and Starbucks and walking distance of the center city of Vienna. Nice tips from your mother for going out to a typical Heuringen-restaurant in the 9e district of Vienna and park the car in this district and doing everything else with the public transportation. Also, the tips given for other restaurants where super, we can recommend Plachutta as a very nice restaurant with a good service!

Thanks for your hospitality
