Niki and her family were very welcoming and showing me around the apartment when I arrived. The place is exactly as described and feels like a home rather than a rented place, which was great since I spent 2 months here. Everything was clean and Niki even arranged a cleaner for me during my stay and took care I had everything I needed. The downside was that it's in a noisy street with traffic, but that's also the trade-off when staying right in the center. There are lots of restaurants and shops around the apartment, and the acropolis and other sights are all in a walkable distance. I'd definitely stay here again if I come back to Athens.
