“Superb”

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.

“Perfect hope to return in the future!”

We swam we ate we dived we drank we explored. Thermia Suites could not have been more perfect. Fave place in our 5 week Greek Island hopping holiday. Aesthetically pleasing, all new quality fittings, comfy bed pillows etc , daily clean, coffee machine, fresh daily Greek Pastries, Pool, large balcony with divine view, ample parking, Hosts were hugely helpful and very responsive. Generous with supplies towels coffee tp etc We encountered some duds on our trip but highly recommend Thermia if your Considering the beautiful Island of Kifnos. Short walk to tavernas bars etc as well as Agius Irini. :)

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.
