I had a great time staying in Petralona at Antigoni and Maria place.
Maria welcomed me at the apartments, explained everything and gave a bunch of tips. Filopappou hill is definitely a must! I found it better than Acropolis or Likavittos because it’s not crowded at all with great views of the city.
I definitely recommend Maria and Anta as hosts - very welcoming and always there to help and advise, and you can find anything you need in the apartments , supermarket is nearby , bakery , many nice places to go to for Greek food.
