9.4/10 Exceptional! (23 reviews)

What a fantastic little resort. We were attending my son’s wedding near Bari and we found this resort and it exceeded our wildest dreams. We just wanted a few days after the wedding to relax and chill. The resort is only 9 rooms but that was ideal, as has masses of space and there were a range of activities on offer if we wanted and there is a lovely pool with plenty of shade. Outdoor dining for every meal if required. Great breakfasts and lunch and diner. The reason I gave it 5 stars (which is unlike me) is the staff, great English, attentiveness and friendliness. Nothing was too much trouble. I would highly recommend if you and a peaceful, relaxing break. Grazie Mille!
