This place is heaven - it's off the beaten track in Sifnos, a gorgeous little fishing hamlet, and you'll feel like you have your own paradise. We'd wake up in the morning early just to have peaceful coffee and breakfast (coffee, toast, jam and more provided by Manolis and Roula) before taking the 1min walk down to the beach for a dip with no one else around. Half the time we didn't want to leave so just spent the day here, going back and forth from the beach to the house's gorgeous deck and then to the fish taverna right where you can pick your lunch from the morning's fresh catch.
The historic aspects (that it's an old pottery house with beautiful pottery everywhere) were so unique and special. And Roula was lovely and left us desserts and more when we arrived. Highly recommend staying here!
Note: having a car to get around would be a great idea, because it's a 20ish minute drive from the nearest town, and way longer to the beaches on the south part of island. It is possible to get around without a car - we took the bus, which was impressively reliable, but if you wanted to stay out past 7pm expect to spend 25euro on a cab back. (& If you're from the US don't forget to get an international driving permit before you leave for the trip - we didn't know it was a thing and no one would rent us a car because we didn't have it!)
