Illias and Danae are Professional hosts with a Capital P. Very responsive and provided detailed directions (and offer airport transfer) to their EXTREMELY centrally located, beautiful apartment. Aside from the apartment being a short walk to the best parts of Athens, it is also fully equipped with all the amenities you'd need, they provide a very warm welcome and are ready to respond with any information about the city you'd need.
This is the kind of apartment I'd rent even if I already lived in Athens because it's so nice.
