Location, Location, Location! Along with top notch service and apartments, maybe the best part about staying with Kostas Apartments is the location. As we stated on our home page, we are located on the beautiful western side of Sidari, along the Saint Yannis Beach. If you click on the Location tab on the top navigation bar, you will see exactly where we are. We are exactly far enough from the center so you can sleep without the loud music and close enough, where a 10 minute walk won’t hurt you.
