Wow, what a wonderful stay in Athens! Lyssandros and Ioanna were such kind, accommodating, and gracious hosts and the apartment was extremely cozy, comfortable, and in such an extremely convenient location. The metro is close and it is very easy to get to dozens of cafes and restaurants and to all the sites you want to see.
I would recommend their apartment to any and everyone that asked and I will absolutely stay there again if I'm lucky enough to return to Athens!
