4 day trip to Vienna
A work conference is taking us to Vienna for 4 days. We will actually be staying above a florist in Vienna, on the first floor of a nice building. someone I've done some research, and I'm sure this beautiful will keep me busy. However, I'm not sure what else would be worth the visit from the capital? Within driving distance? I'm really not that knowledgeable about the rest of Austria. I'm really into history and architecture, and there seems to be a lot of nice medieval cities in Austria. I was wondering what you'd recommend, not too far from Vienna.
Thank you for any ideas you may have!
