The apartment is really easy to find and it was great not to be in the center of tourist-ville. But its really close to everything. We walked to the Panatheanic stadium, around the city center, to the Acropolis and back easily. And you get to find all the little bakeries and interesting shops and street art on the way. We were met at the apartment by Ilias's dad who showed us how everything works and made sure we had everything we needed. The apartment is very comfortable with all appliances, cookery stuff, clean sheets towels etc. and is light and airy. I would definitely recommend this apartment for your trip.
p.s. we loved the lifts, they were so much fun!
