We thoroughly enjoyed our stay in Kate's Emerald Suite. Kate was out of town for the first two days of our stay but her associate Theo was extremely helpful, welcoming us to the apartment, helping us to arrange a car hire and make a dinner booking, and helping us collect our luggage when the airline lost it, then arranging for the luggage to be carried up the hill for us.
The Emerald Suite is beautifully designed and decorated - the romance of staying in a traditional cave house, but with all the modern conveniences. The wifi worked well and the bed was comfortable. And what an incredible view! We loved exploring the little village of Pyrgos, so much nicer than staying in a crowded town like Oia. I would not hesitate in recommending Kate's apartment to anyone visiting Santorini.
