A well-designed and spacious home in the heart of Hermoupolis. It was clean and the check-in went really smoothly and earlier than the official time. It is within a few minutes' walk from everywhere in the town.
However, it is situated directly over a bar and next to another. It is unfortunate that the listing didn't mention that or we would never have decided to stay there. This might be less important for people who expect to come home very late at night, or visit the island during less busy periods.
In our case, we visited Syros during peak season and had trouble sleeping at night. We had to buy and use ear plugs because of the loud music and the noise from the bar customers which usually stopped at around 3AM. The owner was apologetic and tried to contact the bar owners to lower the volume of the music, which unfortunately made little difference in the end.
