Great stay

Stayed in August 2025

Bathroom sometimes had a septic smell, which often happens on the islands.

Beautiful modern and comfortable suites with fully stocked bar fridge, large kettle, Nespresso coffee machine, modern AC, bathrobes and outdoor balcony with a great view. Short walk to Loutra town and beach with lots of options for coffee, brunch, dinner or cocktails. Irene at Reception was super friendly and helpful, and provided a nice bakery breakfast each day, and parting gift!

The shower water would leak into the bathroom and it didn’t drain very well, so the floor would be wet

Very clean and beautiful rooms

Location is good and near the main village. The hostess Eirini was very polite and provided us with many information for the island, thus making our stay magnificent. We will definitely come back here next year.

Overall, our stay was fantastic in every respect. Firstly, the room was beautifully decorated, overlooking the entire Loutra area, spacious, spotless, and equipped with all the amenities a room should have. Furthermore, the service provided by Irini was exceptional—extremely polite and always willing to help with anything we asked for. She also guided us regarding the available options on the island and was available 24/7 for anything we needed. Overall, it is definitely one of the best accommodation options on the island of Kythnos, without any hesitation!

Me and my friend had an absolutely fantastic stay here at The Thermia Suites. The staff was so wonderful and helpful, they went above and beyond for us to have a good time, not only at the hotel but at the whole island of Kythnos. We also got upgraded to the suites, which was amazing. It was so clean and lovely to stay there, the pool was also amazing.I highly recommend this hotel to anyone visiting Kythnos. I’ll definitely come back next time I’m in Kythnos!

Our stay at Thermia Suites was absolutely wonderful, and Michael & Annie, the hosts, made it even more special. They kindly upgraded our room, and the location was perfect—just a short walk to local taverns and the renowned thermal springs. The rooms were exceptional, offering breathtaking views that truly enhanced our experience.

The hotel was in an excellent location - on a hillside overlooking the bay and village of Loutra but close enough to walk into the centre and to the beach. The room itself was tastefully decorated and extremely comfortable. And the hotel staff were very friendly and obliging.

The wildlife was not the friendliest. Especially the sea urchins. We did not get along. The cats were a treat to be around though.

Location is prime. Rooms were exceptional. The staff was incredibly nice and helpful to any issues that arose. The entire hotel was picture perfect and I could not have asked for anything better. The wife absolutely loved it aswell.

There's nothing much to like unfortunately.

The rooms here are not only spacious but also thoughtfully designed, providing all the amenities you could possibly need. From cozy bedding to modern appliances, they’ve got you covered. The attention to detail is evident throughout, making your stay truly enjoyable And more.

great view, big and clean room, nicely designed, amazing bathroom, very helpful staff, the small morning basket with delicacies is a very nice touch instead of a breakfast!
