I have not stayed in these apartments but they come highly recommended by a good friend, and judging by the website (link on my Useful Addresses page) they look very stylish and comfortable indeed. Sadly the website is only in German but the young owners do speak several languages including German, Italian and English.

I have tried their Italian restaurant and the food was extremely good, being cooked by Giovanni, a native Italian, himself. Booking is advised as it can get quite busy.
