first it is important to emphasize that this is not an apartment- it's a room with small fridge and bathroom.
Our stay in this place wasn't pleasant since they "forgot" to change the sheets. we found hair of other people on the bed at 23:00 pm. nevertheless, Ali apologized and tried to make things better. after cleaning the room "properly", we found a cigarette on the floor. I wouldn't recommend this room.
One major advantage of this room is the location- 1 minute walk from U3 to old city and to other parts of vienna as well.
