We had a very nice time in Παγκράτι - Aris was welcoming & helpful and the flat is great.
Would recommend the Black Cat taverna ( lots of locals eat there, good value and friendly), Kekkos cafe ( friendly and delicious homemade cakes & biscuits ), Το Λεξικοπωλείο (international bookshop for adults & childrens titles - on the corner nearby, fantastic!)
