The flat itself was very nice and my host provided excellent information in making my stay very enjoyable. The proximity to the Metro line is outstanding! If you choose, a brisk 15 min walk along the waterfront and you're right in the thick of all the action at Stephanplatz. It's an old building that has gone through a major renovation. There was a bit of a funky musty smell in the corridors, but nothing in my flat. My flat could have used a bit better vacumming, but the hardwood floors helped keep my allergies in check. If you like to keep a window open, be aware that there is a major police station just across the waterway and you will be very fortunate not to here sirens, coming and going at all times. With the outside doors closed, you hear nothing.
