We had an amazing stay with Antonia, mostly because Antonia was such an amazing host, she is very generous and helpful. Santa Teresa is much quieter than Taormina, which is accessible by a train or bus. The town has shops and good restaurants so you don't need to travel for those. The apartment is properly shared with Antonia, but with a private balcony and bathroom. We enjoyed this though as spending time with Antonia was always a pleasure
