Leonidas' place is perfectly located for a stay in Athens. It is right next to the metro station and a quick walk to the Acropolis, Plaka and Monistiraki areas. He was really prompt and friendly with communication and kept us updated throughout our journey despite our midnight check-in.
Once at his place we were greeted warmly by Voulina. She was really pleasant and stayed back to make sure we were oriented and taken care of at the late hour.
I would highly recommend Leonidas' apartment and wish you safe travels.
