Paolo's apartment was a perfect place for our stay in Bologna. It's an easy 5-10 minute walk to the heart of the old city, but is on a quiet side-street so you can rest well at night. The apartment itself feels like a real home, with books on the shelves, area lighting, and comfy furniture, and as we visited in the middle of winter it was nice to have such a cosy, homely place to return to at the end of each day's sightseeing.
Paolo is an excellent host. Communication with him was really easy from the very beginning. When we arrived he took time to sit down with us and recommend restaurants and sightseeing spots, which were all great. If you want to eat well in Bologna then follow his advice.
It's a great place - at the time of our stay there's a chalk-board in the kitchen where previous guests have left messages of thanks, and the positive feeling you get from reading the messages sums it up nicely.
