We stayed at Casa Matteotti for a bit more than a week and we really enjoyed our stay. The location is perfect, on the main Corso of Modica bassa with a lot of options for food and drinks. It’s also quite easy to find a parking spot near the house, even though it’s mainly paid parking.
The house has all the amenities needed for both short and long stays. Two points of improvement: better cleaning of the place before check in and the wifi connection (we ended up using our own 4G hotspot for the majority of the stay).
Overall, I would recommend it if you are planning to stay in Modica or roam around Sicily!
