Breathtaking view is almost an understatement. Completely blows you away when you step out on the balcony. It is a 360 degree view of Athens including the Acropolis. You can shower looking out to the Acropolis too! Enormous balcony by the way, suitable for a mini golf course.
This doesn't take away from the apartment, clean, quite new and really comfy. Has a working lift to get you to the fifth floor and is a pretty easy walk from Thissio metro station.
Location - awesome for tourist sites, restaurants, bars, supermarket...list goes on.
