This is an environmentally-friendly hotel that cares greatly about sustainable growth that has a unique approach to hospitality located in Agios Sostis in Laganas Bay. The hotel is within easy walking distance of the 9 km sandy beach, one of the longest in the Mediterranean, and perfect for exploring the rest of Zakynthos. The place is also conveniently located for the town shopping centre (500 m.) and just 6 km from the airport.
The friendly staff will help guests to hire bicycles or rent a car to see the protected nesting turtles and visit the beautiful landscapes of this, the 3rd largest Ionian island. Otherwise visitors can just sit and relax by the pool and enjoy cold drinks and snacks. A home-made breakfast is provided with freshly-baked bread and cakes, free-range eggs, oranges and plenty of olive oil. Guest's special events are celebrated with a free bottle of wine.
Due to the surrounding area and the number of steps around the hotel, it may not be suitable for those with mobility difficulties.

Wow. Amazing hotel , a short stroll to beach , clubs and bars , great Italien restaurant opposite hotel get card from reception and it gives you 10% off bill . Hotel is family run , friendly and Spiros ( owner , elderly gentleman)is always on hand to greet you and help you with anything .Rooms are big, spotlessly clean we had a swim up in sun from 8am till 330 pm then a few steps into garden for more sun . Food excellent, wide range offered , drinks very good ( only 2 per person but not a problem) .A la carte menu offered 1 visit per 7 day stay, served at poolside very very nice . Would definitely return .. 2 weeks wasn’t long enough .A FANTASTIC stay in all areas 10/10. If you go you will definitely not be disappointed!!! Ps . No sunbed issues either
From the moment we arrived we felt the warmth and welcome of the Hotel. The Reception staff greeted uson arrival, we were given a welcome drink and shown around so we could familiarise ourselves with the hotel.
We were celebrating our anniversary during our stay so treated ourselves to a swim up room, which we loved - we spent many an hour in the pool and relaxing on the sun beds. We also booked an a la carte meal at Eucalyptos to celebrate and this meal was sensationally good.
The all inclusive food was very varied and tasty. The food was always fresh and differed each day, there was always a choice of meats/vegetarian options and a huge selection of salads. My husband is Gluten Free (intolerance) and was generally well catered for. The only repetitive food was desert which was a little limited - mainly a cake or ice cream, but otherwise he had a good choice of foods. If you are coeliac though, I would discuss with the hotel before booking, because there was only one toaster etc, so contamination could be possible. My husband didn't have any tummy trouble at all for the whole week though.
We only used the pool a couple times because we had the swim up pool but it was a lovely pool with comfortable loungers around the edge. There was a bar beside the pool which was convenient and there were snacks but we didn't have any as we were well fed at meal times! Beside the pool was the olive tree area, which we really enjoyed sitting in a couple of the afternoons, and at night it was beautifully lit up.
The jewel in the Castelli crown though are the staff. From the reception staff, to the housekeeping staff, the catering and entertainment staff to Mr Spiros himself (who is always around to greet guests and chat), every single person we came into contact with were smiley, friendly and helpful. Nothing was ever too much trouble.
A lovely touch was a bottle of wine, delivered to our room, on our 25th Anniversary from the Hotel.
We were sad to leave after a fantastic week.
We had an amazing holiday, relaxing and peaceful in our swim up room, which was only 25 steps to the bar through the garden. The food was wonderful and varied daily with a large selection, always with a chef “show cooking”. The owner, Mr Spiros was always sat in the reception area smiling and greeting his guests like family and helpful with any questions we had, he advised us of the best winery to visit (which was a fantastic day out), and he has a great hardworking team who went above and beyond to make our holiday special. There were daytime activities, we participated in Greek cooking which was fun and enjoyed the evening entertainment around the pool. I would highly recommend if you are looking for a relaxing hotel and I can’t wait to return for another visit.
Our 2nd visit which did not disappoint. The food here is excellent, especially the Greek night. Clientele is mainly over 50 and the entertainment is geared around that - low key. The staff and Spiros make this place special, nothing is too much trouble. We will be back next year , please never change.
Had a fantastic honeymoon. Incredibly hospitable hotel with personal attention. Free transfer from the airport. Daily turn-down service with small gifts and sweet cards. Spoiled with breakfast in bed and a bottle of bubbly. Room with a stunning sea view. Excellent housekeeping. All-inclusive package with a very extensive breakfast and a tasty lunch and dinner buffet. Live music every evening. And various activities during the day. The staff is friendly and extremely helpful in arranging boat trips, massages, car rentals, or bike rentals.
Owner Spiros is getting on in years but is always attentive and up for a chat.
Stunning island with crystal-clear water. Wonderful for snorkeling. Nice pool, garden with olive trees, and plenty of loungers.
There aren't many points for improvement. Small bathroom that floods quickly when showering, and a door that opens inwards isn't entirely safe. There is a sufficient selection of soft drinks, beer, and cocktails. However, the wine selection could be a bit wider. Available for a surcharge if necessary.
I have never felt so welcome in a hotel before. Actually, we didn't want to go home. Tip: book directly on the hotel website and not through a travel agency. That way you get an extra discount and are completely pampered.
