The apartment was fine and the location was good. However, Vienna was very hot and so was the apartment. With no air conditioning to cool the room, It was extremely difficult to sleep. And, if you opened the window, the noise from the restaurant/bar below, along with the traffic and trams, it would then be very noisy and still hot. Additionally, the lift kept getting stuck on different floors and the only way to release it was to walk up/down the stairs to where the lift was and give the door a good shake to let it close. A pity, because the apartment itself is actually quite nice, just don't stay there in summer.
