It has a very good location a few blocks from the Ring which is the heart of Vienna. You can park the car on the street in front of the hotel with some luck and go walking to visit the main attractions of Vienna.
It is a residence for students functioning as a hotel may be only in Summer and of that I am not sure. So you can not expect too much of the rooms. But considering all and the price is very convenient and recomendable. The staff at the reception is particularly good, young men probable students.
