Ilaria's place is one of the best Airbnb's we've been to. Located in the very center (3 minutes walk to piazza Maggiore), very bright, light and stylish. The street is very quiet, and we had good night sleep. The apartment is spacious, we were two and there was a lot of space for us :) kitchen is small but very well equipped. As someone who loves cooking, I was very happy to see all kinds of tools, spices, condiments and different kitchenware. With Mercato dell erbe nearby, you can cook basically anything in this kitchen!
However, there are two negative-ish things I want to mention:
Hot water is mmm capricious. You need to wait for several minutes for it to start running, and a good five minutes for it to come to the kitchen...
Information inside the apartment. Ilaria gives great advice on restaurants and sightseeing places, but basic info is lacking. Please double-check the WiFi code, the one on the wall was wrong when we were there.
All in all, our issues were mainly due to the lack of communication, hope that it was an exclusion, and that other travellers will have more chance :)
