My parents and I stayed at Bene's place for 3 nights and had a wonderful time in Vienna! Communication was great and he even carried a bunch of luggage up the stairs for us when we arrived. We were there during a heat wave and when we asked if he had a fan, he brought one over the same day. A couple words of advice: the apartment is on the 3rd floor (4th floor in the US) and there is no elevator so if you have someone in your group who doesn't do stairs easily, it's not the best location. Also when we arrived, we parked the car on the street in front of the apartment for not more than 20 minutes to unload, and by the time we came back, we had gotten a ticket. We knew we were taking a risk but didn't realize just how efficient parking officials are in Vienna! So make sure you pay to park even if you're just staying for a few minutes. Overall I would highly recommend Bene's place. The location is amazing and almost all the best sights are within a 15-25 minute walk.
