I totally recommend this apartment. It is perfect if you stay for a couple of days in Athens.
The location of the apartment is great, because there are many shops and bakeries nearby. Moreover, almost every major sight is within a 30 min walking distance so you don't need to use public transportation.
Considering the flat is a lowe price Airbnb it has everything you need and exceeded expectations. The apartment was clean and Vasilios prepared everything really nicely (food and drinks as well).
Vasilios was a great host and a really cool guy. He always replies within minutes and is happy to help with all the struggles you might have.
If I come back to Athens, it will be at his place again!!
