Kostas is an exceptional host, answering my messages promptly and warmly. He arranged for a trusted taxi to pick me up at the airport. Kostas was waiting for me at the flat, and spent time showing me a map of Athens and where things are. He has a list of emergency contact numbers and information, which is very thoughtful. He checked on me to make sure I was happy, made sure I had plenty of towels, and even checked on the ferry status when I was leaving to help me come up with a plan if weather cancelled the ferry. As he told me in one message “I leave nothing to chance.” I wish all hosts took some training from Kostas on planning and hospitality. And, the flat is comfortable and conveniently located, safe, and very clean.
