Liz & Jules apapartment is, with no doubt, the best option to stay in Vienna.
Their place is way much better once there than in the pictures.
It's a modern, stylish, neat and complete furnished apartment where you can find all you need.
There is a potent wifi connection and it's located in a quiet residential area with plenty of all kind of food restaurants.
I stayed with my parents, who are over 70, and all of us felt very welcomed by Liz who met us for both the check in and the check out as well as for all the doubts and questions we had.
The public transportation, subway, tram and bus as well as taxi service is just two minutes walking. But it's not actually necessary since downtown is in a real walking distance and the walk to the center is completely worthy.
I highly recommend this apartment!!!
