Book it!!
Ilias's spot was perfect for us! We loved the neighborhood which is mostly filled with real Athenians, and only a 12-minute walk from the super-touristy, but fun neighborhood of Plaka as well as the Acropolis. There is a cute pedestrian street just 1 minute down that has lots of great restaurants, and Ilias showed us where there is a farmer's market a couple of days a week. I also appreciated that there are numerous independent artisan shops within blocks of the apartment.
The apartment itself has everything you need to be comfortable. The weather wasn't great while we were there so we didn't get to enjoy the patio, but it was lovely.
Ilias is a very communicative and helpful host. He patiently explained how everything worked in the apartment and was very responsive when I messaged him with the occasional question.
I'd jump at the chance to stay in Ilias' place again!
