Sophias Place is as comfortable as one might imagine from seeing the pictures. It's a very nice and quiet appartement. And in an area with lots of places of reasonable good food, a warm atmosphere and kind people in the neighborhood. There are places in Athens at night were one might not want to go, but this ain't one of them.
The tube isn't afar and possibilitys to get good cheap wine and groceries are near.
So if you're not interested to live in the chaotic center but still want to be near, it's a great choice.
