The appartment is on a big street but we didn't heard anything inside ! The AC is very well working so we could take a break from the heat of the city in July.
There is a lot of nice restaurants and bars near the place (5 minutes away), also a bakery and the public transportation (metro) is 10 minutes away maximum. The must of the apartment is the view of the Acropole of Athens and the Parthenon !!
The appartment as itself is very clean and spacious and you will find everything that you need at your arrival !
