The place is in a perfect location, close to Zeus temple and walking distance to monastiraki, sintagma square and many other wonderful spots. I only had an issue related to a request “paying of course” for a late checkout that was refused the day before my departure and that unfortunately given my disability made things a bit complicated for me. That said, yes do book with Kostantino as the place is really nice and welcoming and overall I can’t complain neither about the host nor the place.
