We stayed with Stephanie and Makis for 2 nights. I would recommend anyone who wants to visit Sifnos should stay with them. Its clear they have a passion for the island and gave us great suggestions as to where to visit and how to get about.
Makis picked us up from the port even though it's only a short walk, it was part of their fantastic hospitality and a lovely touch to make you feel welcome.
The room was clean and comfortable, with a nice balcony looking out towards the bay. The beach is about than 50 metres away.
If we return to Sifnos in the future I know where I'll be staying!
