Clean and nice place to stay. Didn't have any issues during my stay. Kostas is mostly reachable always via whatsapp. The area looks a lot safer when compared to other metro stations like omania and victoria.
It is little far from the center of Athens and need to take the electric bus. From the property the bus is less crowded but back to home it gets very crowded. Uber taxi is always available, so we used them for our travel to the day cruise and the port.
