Castelli Hotel Adults Only - All Inclusive

In Agios Sostis on Zakynthos’ southern shore, a short walk from Agios Sostis Beach and close to Laganas Beach. This adults-only, all-inclusive boutique hotel sits near the Ionian Sea and the National Marine Park of Zakynthos — perfect for turtle-spotting and island days.

A family-run, adults only boutique with 54 guestrooms and a cosy, eco-minded vibe. Rooms include refrigerators, private bathrooms with designer toiletries and hairdryers, laptop-compatible safes and desks, and many feature balconies or terraces. Standouts here are pampering swim-up rooms, a preserved 200-year-old eucalyptus at the heart of the design, and on-site farm and botanical gardens with olive-picking, cooking classes, yoga under the olive trees and other local activities.

All-inclusive comfort with a seasonal outdoor pool, hot tub, swim-up options and a poolside bar. Pamper with onsite body treatments and facials, rent bicycles for island rides, or join hiking, diving and farm tours. Expect concierge service, bike parking, a library corner and a relaxed, green setting — and wake up to sea-breeze mornings near the park and shore.

Complimentary wireless internet and a computer station keep you connected. The hotel also offers luggage storage, dry cleaning and laundry services, plus an airport shuttle available for a surcharge.

All-inclusive dining with a Mediterranean focus. Enjoy the award-winning Eucalyptos A La Carte and a main restaurant serving farm-to-table Greek cuisine using on-site organic produce. Buffet breakfast is served daily (07:30–10:00), with lunch and themed dinner buffets, pool snacks, afternoon coffee and cake, drinks service (10:00–23:00) and unlimited ice cream at the pool during service hours. Special-diet options like vegetarian, vegan and gluten-free are available on request.
