We stayed at Zoe's for only a night (as we had an early flight the next morning), but her place was worth the price! She was very accommodating and communicative beforehand and even made sure someone was there to greet us when we arrived!
I would recommend this place if you need an affordable place to stay in Athens. Neighborhood was nice although we didn't have much time to explore. It felt local and authentic as the next morning there was a giant farmers market outside the apartment!
