We had a wonderful stay, with amazing views across the island that made the experience truly memorable. Our room was tucked away in a lovely, secluded spot with beautiful garden views, offering a peaceful and relaxing atmosphere. The staff were exceptionally helpful, friendly and accommodating, always willing to assist and ensure we had an enjoyable stay. Although the location was a little out of the way, it was only a short taxi ride of approximately €9 into Argostoli town, where we found an excellent array of restaurants, cafés and shopping options. Even late in the summer season, the town still had plenty to offer, with a lovely atmosphere and lots of choice for dining and exploring. Overall, we thoroughly enjoyed our stay and appreciated the beautiful surroundings, attentive staff and convenient access to Argostoli. A lovely place to stay while exploring Kefalonia!

Excellent hotel. The room was a good size and clean (we stayed in one of the far buildings, looks like they've had a fresh refurb) and the food was some of the best we had on the island. The staff were super helpful and friendly. The pools were lovely and there is access to a few beaches nearby - a relaxed 5 mins walk (max). The sea water was some of the best I have swam in. The gym was a good size and perfect for exercise snac whilst on holiday. If I was to pick I'd say the only thing needed to improve that stay was new exercise mats! I would 100% recommend.

Thalassa Boutique Hotel is a very nice property. The rooms are a good size with a nice balcony. It offers two pools, a very nice outdoor bar/lobby and a wonderful restaurant. I would say the only setback was the construction right across the street from the hotel which made the road to the beach dirty and dusty. Honestly we found Costa Costa beach which is a 9 minute walk and we went there every day bc it was fabulous. The rooms are very clean. They change linens and towels every day and the cleaning staff is so sweet and friendly. They come into your room every evening, get the room ready for the night, leave Leonidas chocolate and water bottles Breakfast is included in the price and there are a lot of choices to pick from. The restaurant offers a Greek night with live music which we attended and had a lot of fun. It also hosts a barbecue night with a fixed menu and price. I would definitely recommend this hotel if you go to Kefalonia

The pool area was beautifully landscaped with olive trees, gorgeous flowers, plants and an abundance of rosemary. We did feel a little disappointed the pool was within the hotel rather than facing out to sea. It gave the impression the hotel could be anywhere. Visitors need to be aware of the construction work below of a new, very large hotel. Only the roofs are visible fortunately, but there is some noise if you go to the nearest small beach. The restaurant was excellent on the few times we went.

Absolutely fantastic adults-only hotel! From the moment we arrived, everything was perfect. The peaceful atmosphere made it the ideal place to relax and unwind. The staff were incredibly friendly, attentive, and always willing to help. The rooms were spotless, spacious, and beautifully presented and loved the fact that they had smart tvs in the rooms, so we could watch Netflix and Amazon prime on an evening and when getting ready in the morning, every detail was thought of. The food and facilities were excellent, and it was so refreshing to enjoy a calm, child-free environment. A truly relaxing and luxurious stay – we left feeling completely recharged and can’t wait to return. Highly recommended!”
