I absolutely love this place! For me it’s the perfect hotel - adults only, not too big or small, gorgeous outside, communal spaces and rooms, and great food and drinks. The staff are all so friendly and accommodating as well - nothing feels like too much. We had a late flight and so paid a little extra for a late checkout and we were upgraded to a swim up room for our last day which was the perfect end to our stay. The newly opened spa and gym were also a great addition and we used them a couple times during our stay. Lastly, the local area was also really convenient with a beach, shop and restaurants all within minutes away. We’ll definitely be returning soon!

Staff were super friendly and very accomodating. Room was nice with a comfortable bed. Food is lovely too. The only negatice thing is the noise from the beach bar down the road. Music goes on until roughly 12 a.m. There was also construction noise going on next door and gardening noise in front of the spa.

Amazing hotel!

Best hotel in Kos! Everything was amazing, and the service stood out. The staff was beyond friendly and took the time to help find us local dinner reservations, walk us through things to do on the island, and answer our many questions. Maria was so kind! I did not get the name of the other girl at reception, but she was also so helpful! The atmosphere and amenities were top tier. We decided to upgrade to the room with the private hot tub which was very much worth it. The breakfast was also top notch. Worth every penny and would stay here again if we return to Kos.

A lovely relaxing hotel, primarily set up for couples. Setting and ambiance are spot on, always feels quiet and like you have your own space. The styling of the hotel is quite unique and very contemporary, it helps to create the right atmosphere. I would definitely stay again, we had a shared pool, which worked well, glad I didn’t go for the private pool, as all the pools a quiet enough. Rooms are very well attended and cleaned. The hotel serves one of the best breakfasts I have ever had, great setting, service and choice. Only negatives, the gym is very small and one of the treadmills was broken all week. The same goes for the Hammam, which was being fixed all week. Also, at times the staffing can be minimal and drinks take a while, but generally the staffing is very good.

From the moment we arrived at Theros All Suite Hotel, we knew we were somewhere special. The atmosphere is pure serenity — calm, elegant, and beautifully designed in natural tones that perfectly capture the spirit of the Greek islands. Every corner feels thoughtful and harmonious (inc.the gym!). Our suite was stunning — with a Swim Up pool that made each morning feel like a little paradise. The attention to detail is remarkable: from the high-quality bedding and rain shower to the soft lighting and music throughout the hotel. The staff truly make this place unforgettable. Everyone we met was genuinely kind, professional, and attentive — going above and beyond to make our stay perfect. A special thank you to Maria, who was always there with a big smile and the best recommendations for restaurants and places to explore around Kos. Her local tips made our trip even more memorable. And Sergio was fantastic — always ready to help with anything we needed, friendly and professional. Breakfast was delicious and beautifully presented every morning, with fresh local ingredients and plenty of variety. Great lunch/dinner too. Location-wise, you can’t ask for more: a pleasant walk/short bike ride into Kos Town for restaurants and shops. It’s peaceful yet perfectly connected. The hotel is a true haven for relaxation — elegant, quiet, and full of heart. We left feeling completely recharged and already can’t wait to come back. Highly recommended to anyone seeking luxury & tranquility!
