Excellent value for money, located just above a "U-bahn" subway station (Trains run well below the ground, so you can't hear it but you can take advantage of it's convenience) in a multicultural neighborhood.
The apartment is in a building with a lot of character and has the charm of a bygone era. Inside, the flat itself is recently, tastefully renovated in a quasi-minimalist, yet cosy style with every amenity you can think of. The kitchen is fully equipped and well stocked.
Simon is an excellent host and his communication was very good. I hadn't the pleasure of meeting him personally but his sister took care of check-in and check-out in a gracious, flexible and efficient way, while Simon kept in touch with me throughout the whole process.
I definitely recommend his place to anyone visiting Vienna
