We loved our 5 nights in Santorini, however 3 nights would be plenty as it's small. Fabulous location for sitting out on the deck and watching the sunset. Beginning October we weren't lucky with the sunsets as was too cloudy in evenings but still a beautiful setting. Not suitable for cooking as you do feel closed in when inside as it is a cave house. We had a great meal at karma. We enjoyed the deck, took quad bikes for a day which was a highlight, and walked to Fira another day.
