With one of the best locations in Athens on the wide and airy pedestrianized Makrigianni street, with reasonably-priced cafes and restaurants a few feet away, the Akropoli metro stop across the street, a partial view of the Parthenon from one of the windows, the Acropolis ticket window within a 5-minute walk, and none of the tacky tourist junk shops and barkers one finds in the Plaka district, I cannot think of a better situation than this apartment.
The apartment is very clean, with a separate bedroom and separate living room with a sofa-cum-bed. John is a friendly and very helpful host. The pick-up taxi service John mentions on the web page is exactly the same price as if you were to book it yourself and about the same as hailing a taxi at the airport. The only very minor concern we had was what appeared to be motion-detector monitoring devices in the rooms, something that may concern guests with a fervid imagination. Perhaps John can respond to this review by reassuring future guests that these are nothing more than security devices and intended for no other purpose.
All in all, I would say that this was "find."
