We had a great stay in the Cave House at Ersi Villa. Elias was great, picking us up at the bus station and then driving us back there when we departed. He was also helpful explaining things to do around the island. The Cave Room was very nice with great A/C. The only complaint I would, which isn't a big deal, is the wifi isn't good in the room. However, there is a private patio just outside the room where you can get excellent wifi. We would definitely stay there again.
