We stayed here 2 weeks in late Sep/early Oct. The place looked just like it does in the photos, a bit better even in person, we loved the spot in terms of a workspace and a place to relax. If you're planning to stay in Sep/Oct it is NOT quiet during the day as a lot of the surrounding farms are in prime season it seemed, people hunting quail so shotguns in the morning, people presumably farming all day, and lots of chainsaws on surrounding farms. When those things were not occurring, we very much enjoyed our time here as it a peaceful and quiet. One key thing we found a bit annoying especially since it was not advertised was that the water was not potable. We spent a good deal of money and a good deal of waste on bottled water for our stay, which we did not love. Also, if you are very allergic to hornets/wasps you seriously need to have an Epipen available as we both got stung during our time there (Asian hornets got into the house which was a pretty hilarious time having to get them out). It is rural enough that that would be a concern without one. You 100% need to have a car if visiting here, it's non-negotiable.
Michelle - the property manager - was responsive, so no problems there except just keep in mind he really does not speak English so it's a google translate conversation, but that was easy to navigate.
The location of the place really is dead center to most of Puglia. Ostuni and Cisternino are super close and both were beautiful, we ended up going back to both towns multiple times because of convenience and the food was so good. Lecce is only an hour and a half drive away tops and there are plenty of beaches within 1 hour drive that are gorgeous. Illaria was accommodating to date changes we had last minute with Air France being Air France and canceling our flight, I'd recommend this place if you are ok with some of the smaller caveats!
