My friend and me stayed for one night in Antonios apartement during our backpacking tour through Greece. Even though, our ship was late and arrived at night, Antonios picked us up from the port and showed us the way to the apartement. He made us feel very welcome and was super friendly and helpful. The apartement itself is small but there it is enough space for two people, especially if you are spending most of the time outside exploring Syros. Everything was clean. Unfortunately we could only stay one night, but we will hopefully come back soon to stay a bit longer.
