Lefteris was great. I left a day early to catch a ferry to Karpathos but I plan to look for more openings at his place once I return to Athens. Historical Plaka is merely a 15-20 minute walk away with the Acropolis possibly another 5-10. It’s noisy in the area but from what I’ve gathered that is Athens for you. There’s a cafe right down stairs open everyday but Monday. There’s plenty more taverna’s and cafes on surrounding blocks. You have two metro stations each around a 10 minute walk away. Highly recommend staying at either of his listings.
