Panos is a perfect host. He was super friendly, helpful and always available. He gave us a lot of information about what to see and visit in Athens, where to go out and where to have good traditional dinner.
The apartment is very cosy. It was exactly like described and very clean. The location is a dream, very central. The major sightseeing locations are easy and fast to reach. From the balcony, you have a really nice view on the Temple of Zeus.
