We had a great stay at this large apartment in an excellent 1st District location. Public transportation by bus is about 30 seconds from the front door and the U-Bahn is about 5-6 minutes on foot. The entire inner city is easily reached without taking public transport and has plenty of great window-shopping and sights along the way. There is an excellent gourmet grocery (with wine shop) within 1 block and plenty of specialty shops and restaurants close by. We spent quite a bit of time in outer districts and had no trouble getting to the right streetcar or U-Bahn.
With many windows, we had a great view but were high enough on the 6th floor not to be disturbed by any noise when the windows were closed (our stay included a weekend). All the windows have shades if you need privacy or to keep the sun out. The flat has plenty of lighting and storage, including ample places to put your things. Plus, there is a coat closet at the entry and a handy key hook on the door. The bed was comfortable and the sheets good quality. We appreciated the addition of dish soap, tea towel, & sponge for the kitchen sink. There's also a coffee press if you prefer to make coffee (Vienna has lots of excellent locally roasted coffee). There are about 8 steps after entering the building to get to the elevator.
Overall, the apartment is as shown in the listing and we very much enjoyed our stay here.
