Kleio is a one of a kind host. Both my sister and I had not had an experience like this before. Check in was really smooth, she came and welcomed us was extremely welcoming and kind. She should us a lot of places to go and gave great tips on where to go. The most impressive part was how responsive she was through out the entire trip. She even went the extra mile to inform us the metro would be on strike and arranged for our transport to a tour we signed up for in order not to miss out on anything. The place is very clean and so close to the metro it makes everything within reach. We will definitely stay here next time we are in Athens.
