Konstantinos’s place was good. It’s in Oia, which is the second largest island of Santorini, but almost no shops and restaurants are open in January, so it’s not convenient. The house is 2 minutes away from a little grocery store and 10 minutes away from a bus stop. It has an A/C but still very cold. The WiFi was very slow, on and off from time to time. The hot tub was great, very relaxing. Konstantinos arranged a pickup transportation for us, which cost double than the taxi we hired for the drop off transportation. Not recommend Santorini, not worth it.
