Excellent location, roomy home, friendly host.
Coming from the US to Athens for the first time I didn't know much about where to stay but Konstantinos' place is ideal. It's an easy walk to the metro but honestly you can easily walk to much that you want to see and we only used the metro a little. Lots of great restaurants nearby (check out the great cheap eats at the place across from the metro). Konstantinos was warm and easy to work with. You won't regret staying at Konstantinos'. We would love to come back again.
