Eva welcomed us into the apartment and showed us the particulars and provided us a map of Vienna along with recommendations for restaurants and shops near us. The location is great being 2-3 blocks form the Opera house and 1 block from the large Vienna market.
The stay was great and we would use Eva's apartment again.
Note as in most locations in Europe there is no air conditioning, but fans are provided. Apartment is on 6th floor (there is an elevator) so was a little warm which is expected in June July time frame.
