Georg has a beautiful and spacious apartment next to the Mariahilfer Strasse corridor. His unit has everything you could possibly need for either a short or long visit to Vienna. The unit is situated around the corner from an U-Bahn station that takes you directly into Old Town within minutes. There are plenty of places to eat, drink, and shop within walking distance from his unit (Naschmarkt is just a short, 10min walk away).
Georg was very hospitable, accommodating my arrival from Prague to meet me at his place when I arrived before he had to leave for the Christmas Holidays. His communication was excellent, prompt, and accurate.
I highly recommend staying at Georg's place for your visit to Vienna. His unit is modern, stylish, and very spacious. You will not be disappointed.
