Like so many others already stated here, we just loved our stay with Efi. She was a wonderful host, telling us about her beautiful house and her family's history on the island while inviting us to a coffee on her patio. She even send us off after our (far too short) stay with lemons and homemade jam.
The apartment was spacious, cool and furnished with everything we needed to cook and feel at home.
The island was also great, with a small beach just a couple of minutes from the flat, some small shops and restaurants right around the corner and secluded hiking paths that lead you around in the mountanous but green landscape.
It's a great start to visit the cyclades or even to stay longer if you are looking for a relaxed and enjoyable time.
