This is a great apartment: very clean, well equipped, comfortable beds and quality linen, with a balcony all around with open views on the streets. We couldn't have hoped for a better place for our family of 4. Kolonaki is a great area, with cafés, restaurants and upmarket shops of all kind. Most sights are walking distance. The traffic can be noisy but that is to be expected for this area. The hosts were welcoming and discreet. I would recommend the walk up to Lycabettus' hill nearby for fantastic views of Athens.
