We stayed one night and found the apartment as described. It was well equipped and welcoming in an older building on the third floor up a winding stone stair. Would recommend staying longer as everything you need is there. It is very close to an underground station which is convenient for going into the City, out to see the Schonnbrunn Palace and heading for the airport. Good breakfast and market food available in the Naschmarket very nearby. Helpful host throughout the process.
