We visited Syros and we stayed at Kostas place for 4 nights. The house is really nice , exactly as seen in the pictures. It is well located, 5 mins walking from the main square, but there are some stairs that people have to take (in case there is a person with movement disability it might be a little difficult). Kostas was really helpful and kind. He picked us from the harbour and helped us transferring our luggage to the apartment. Furthermore, he provided us with useful information regarding the best places to visit and eat. I definitely recommend his place to other people.
