The place is ideally located around 8 min walk from Syntagma station. You can walk to every major historical site. There's also a big rooftop and the place is super clean. Despite the central location and proximity to bars and restaurants it's very quiet and calm so you can really rest and relax. There's no kitchen and you cannot cook in the place so it's perfect for short stays when you want to eat out. Also Panos is really nice and very responsive to messages. He offered me some delicious greek cakes and provided many nice local addresses. I definitely recommend this place !
