Artemis's place is value for money for those wanting a budget trip. It's not facing the Caldera though but rather the sea. Some of the room though would not be able to have the sea view as it's facing the road. The place is nice and cosy. The host is very prompt in answering questions. But I'd say not very friendly. They do get a little frustrated if you ask too much questions but they will still assist you with a forced smile.
All in all if you're trying to save money and finding a good location this place is not bad.
