Parimin

This store is like walking around in an art museum, it is so beautiful! They have a very big selection of all kinds of books, including lots of beautiful picturebooks.

For Greece, they had a quite nice selection of silent books (the interest for these books is growing in Greece, but still not a big part of the picturebook culture). It took some explaining to communicate what I was looking for, but as always, Google translate is your friend  :) 

Well worth a visit, and make sure to take the elevator while you are there - it is an experience! If you are travelling with children, there is a very charming toystore right across the street from Parimin that you might want to visit as well.
