1. it was my first airbnb tried in Athens so I can't compare with other locations but i think this one is super good for the turistic points like Acropoli, Stadio, National garden, city center in general and also for 2 metro stations (syggrou and Acropoli)
2. the apartment is modern, really good sound isolation, kitchen super full equiment, bed with confortable matress, warm blanket and large-confortable shower. also the hiters work efficiently. the big balcony is a plus
3. I think you can find cheaper apartment but this price is fair for all this features.
