Ioanna and Lyssandros are the perfect hosts. Communication was really good and responses came quick. They organized a transport from the airport and waited for us at the apartment to show everything to us. They also gave us good recommendations for our days in Athens and tips for some authentic restaurants which turned out to be really, really good!
Even if we left quite early in the morning Lyssandros came again to ask us about our stay and make sure that our transportation arrives on time.
Also the apartment itself was clean, well-equipped, has comfortable beds and a perfect location within the student area of Athens which we liked much more that being at Monastiraki for example.
Overall I cannot imagine better hosts and a better place in Athens.
