Kleio's place was awesome! She arranged transfers to and from the airport and greeted us when we arrived at her home. She spent time with us and gave a lot of recommendations for places to visit and eat after showing us all of the amenities.
The apartment is about a 10-15 minute walk from the Acropolis and many, many restaurants. The apartment was thoughtfully designed and had so many excellent amenities (washing machine with dryer, Nespresso, and a great shower!) The neighborhood was very quiet and was close to a lot of landmarks and was easy to navigate to via cab and on foot. I'd love to stay again if we find ourselves in Athens!
