Incredibly spacious & airy; breathtaking views. Overlooks the city as well as a nice little forested park that is good for strolling in, or heading west thru a sylvan setting instead of a city street. A good variety of restaurants are close nearby, and a large full-service market is about an 8-10 minute walk away. Incredible views of Athens, the sea in the distance, mountains, Lycobettus, and the Acropolis. Trees & birds; you feel like you are in an eagle's nest high in the sky. It's a bit of a hike to the metro -- about 10-12 minutes, but if you like to walk it's great! We even walked to Monastiraki, the Acropolis, Thissio etc. though it takes about 25 minutes... but you can spend some of that going thru the National Garden if you plan your route right. We walked to Kolonaki & Lycobettus many times -- about 12-15 minutes. There is a large jacuzzi tub that was very welcome after long days spent exploring Athens on foot.
Zena is a lovely person; soulful, and responsive.
The only caveat about the apartment: Zena has some designer acrylic chairs surrounding 3 sides of her very large dining table in the beautiful kitchen (5-star views in 3 directions!); she warned us of the fragility of the chairs... a guest had broken one. We sat on them as if they were Louis Quatorze antiques, yet near the end of our 3rd week the back of the one I was sitting upon snapped completely off at the seat, dumping me backward onto the floor and putting a gash in my thigh from the sharp broken edge of the seat. Zena was quite upset; she didn't ask me to pay for the chair (tho' I think she expected me to); the bottom line: she loves her chairs very much and plans on replacing it, but if they're still there I would advise avoiding them. We brought a desk chair in from the living room for the "acrylic" side of the table; the other side has a lovely wooden settee.
Better safe than sorry.
