Great host & apartment!!!
My family of 4 full adults stayed at the apartment.
Our host, Tamara was so kind that she welcomed us even at our late arrival at 24:00 hour!! She also gave us helpful information about surroundings.
Her apartment was clean, spacious for my family and had everything we could think of: washing machine, hair dryer, various spicies for cooking, etc. The apartment is located at the very center of the city and many tourist spots are in walkable distance. At the same time, since it is located at the center, it could be a bit noisy at night though it didn't last whole night.
I would definitely book her apartment if I get to go Athens again.
