The apartment is in an excellent location - right by the acropolis but also easy to walk to some less-touristy areas as well. We went to a few amazing restaurants that were just a few minutes away!
The apartment itself is clean, stylish, comfortable, and cozy. It has an adorable little balcony and even a laundry machine to wash clothes. The only negative is that the shower didn't really produce hot water, so if that's important to you then it's something to note.
Giannis was very responsive to any of our questions and very friendly! He also helped me get a taxi and went above and beyond to be helpful.
