The room was excellent,well placed,5m walking to the city center, 1m to the port and the bus station.
The lit was the most comfortable we had and we have really appreciated, the only thing was that the shower is a little small so If you are a big person,you may have to have your shower with the open door 😅
Downstairs there is a nice taberna where you can eat from 10 am to 12pm so it can be a little noisy if you let the windows open but there is an air conditioner so no problem.
Syros it's a beautiful island with nice little streets with great restaurants and I wouldn't hesitate to recommend Kostas place to enjoy the island.
