We stayed at Villa Theros as a group of six for nine days in September.
I cannot reccommend it enough. The accommodation is spacious, tasteful, equipped with everything you could possibly need and it is brand new.
It is in a peaceful yet convenient location about a 5 - 10 minute walk from the local village and beaches. The views over the surrounding are and sea are amazing. Michalis and Vaso were so friendly, fantastic hosts and seriously went above and beyond to ensure our experience was the best possible. Their advice on where to explore on the island was also invaluable.
Overall, a fantastic experience and would not hesitate to return.
