The flat is in a wonderful location with only a short walk or tram ride to the major station Landstrasse. The apartment was very clean and the decor and amenities were top rate.
Note that there is an elevator to get to the apartment to help with luggage.
I will also mention at night you can hear the trains go by if you open the windows but it was not very loud and if you are already from a big city then the sound is very soothing.
