This apartment in the center of Athens is not large, bet very commodious. Bed was comfortable, Wi-Fi was fast and stable, we had all amenities we needed to make food - fridge, microwave, all the cutlery. Nice touches were a bluetooth speaker and large FHD TV with Netflix support, so you can watch Netflix using your own account.
Location is very good, too. It is close to both main squares - Monastiraki (very close) and Syntagma (a little bit further, but still close).
Tip: the closest supermarket is AB Vassilopoulos (Mitropoleos 72).
