Jelena’s place was very nice. Located between the center and Schönbrunn, so it’s not that far away for the things you might want to visit in Vienna.
Also the apartment had a vintage feel to it, but had all the modern amenities you will need. Jelena was also very responsive whenever you have a question, and the description she sent for checking in was very helpful.
One thing we didn’t notice though until we were there, is that the apartment was on a higher floor (2nd or 3rd) with no elevator, but it was very easy to climb if you don’t have heavy luggage with you.
