I have been three times at Ariadni Hotel so far (August 2017, 2018, 2020). It is a family-owned hotel that has also umbrellas and sunbeds for its guests. It is near the Arvi beach and at a walking distance from the local taverns and bars. The rooms are not large, but they are clean and each one of them has the air conditioner. And you can have a complete breakfast, too!
