Four of us had a lovely 10 day holiday at Villa Alma. It is ideally suited for visiting Syracuse & Ortigia and the views from the upstairs terrace are incredible. There are a number of excellent restaurants within a short walk - though care is needed as the road can be busy at times.
Also within easy driving distance are the cities of Noto & Ragusa which are well worth visiting; the latter best approached via the mountainous area to the west of the villa.
We were two couples and would recommend asking for a second set of keys as the security of the villa meant if one couple went out, careful planning was needed.
The villa is good value for money and reasonably well equipped - we did little self-catering apart from tea/coffee and picnic type lunches.
