Masseria Agnello was one of the nicest places we stayed at during a recent trip to Sicily. As other reviewers have said, it is a newly opened property, open only since June 1, 2015. We were told that the owners have been renovating an old farmhouse and other buildings for at least the past decade, and they put a tremendous effort into it. It is modern, with large rooms and new fixtures, perched on a hill with a beautiful view of the surrounding area. There is a common room and dining room on the ground floor and a wine bar across the courtyard. Our upstairs room was quite spacious and we had an outdoor terrace to ourselves to share a glass of wine in the afternoons. They also served meals that were cooked in a gourmet kitchen on site, and the food was outstanding. Apparently adherents of the slow-food movement, much effort was put into serving locally-sourced and individually prepared meals. They also had an excellent wine selection, and we tasted olive oil and honey produced on their farm.
It was difficult to find, all GPS and online maps giving incorrect information, but a phone call was all it took to put us on the right track. If you are going, these GPS coordinates for the turn-off from the main road may be helpful: N 37.32705, E 013.46103. From here follow the signs to the top of the hill and turn left, follow the road to the property on the right.
