I recommend this appartement. Great location in Athens, close to the acropole and the different points of interest but the area is quite ans safe.
Everything is walking distance, but you can also use the metro nearby. Also, there is a supermarket and a pharmacy in the street, and a bakery 1 min walk from the apartment. And good place to have breakfast just down the apartment, at the corner.
Apparement is small but very clean and confortable.
Only the wifi was not working very well but it was not a problem as there is wifi in all restaurants in Athens.
Would definitely come back.
