Blue Calm is one of the nicest Airbnb's I've ever stayed in and Stelios is definitely one of the best hosts!!! Everything is first class from the decor to the amenities. The location and view are spectacular and did I mention how great of a host Stelios is? Our only regret was not staying longer. Sifnos is an absolute paradise and there is no better place to experience it than Blue Calm!!! Thank you Stelios......we'll be back. :)
