Clean place, not touches. There is mobil internet device provided which you can connect wifi and carry out with you in the city. Was perfect. We liked the flat itself and store our luggage in the building after check out. However Operngasse is a long street. You have to walk 700m to reach Opera haus, which is not far but then need to crosss so many busy roads, it takes 15 min to get there. I did not enjoy exact location but Turkish kebap place downstairs is certainly recommended.
