Asterias worked well for my time on Santorini. It was basic, and comfortable. Hot shower, Air Conditioner, laundry service for $5, fairly minimal kitchen amenities, decent WiFi. Close to the restaurants and Perivolos beach. Probably about a 5-10 minute walk (I was always on my scooter, so I don’t know for sure). Maria helped me rent a scooter, and organize my transport to and from the apartment. She even invited me to her music rehearsal with her friends, a highlight of my time there. Another highlight of Santorini was the outdoor cinema in Kamari. NOT to be missed.
