We loved Syros and this little house! It’s literally situated 5 min from the sea: from the terrace you have a stunning view towards the sea and at night the waves accompany your sleep. The house in itself is small and simple, but it had everything we needed and is very clean. Victor was very helpful and gave us a lot of good tips on what to do on the island and where to eat etc.
Syros might not be the most beautiful island of the Cyclades (except for the capital Hermoupoli!) but we found it very charming and relaxed, also tourism isn’t as omnipresent as in other places.
Ah, as for the beach next to the house, it’s small and nice but when the wind blows swimming isn’t recommended there. But with the scooter you can reach other nice beaches in 10 - 20 minutes!
