We stayed in Andronike's house for two nights. Andronike was stellar with her communication, arrangements for us to be picked up from the ferry (which was late due to the weather) and receiving us very graciously and informatively.
The apartment is absolutely wonderful. It has all the facilities - washer, additional heaters, microwave, coffee makers etc. The furniture is tasteful and useful. The beds and linen were top notch. Little things were taken care of - like instructions for the washer and switches for the water heater etc.
The apartment location is unbeatable!! It is pretty much as close as one can get to the Acropolis museum, Acropolis, Filopappou Hill (my favorite place in Athens to view sunsets and the lighting up of the Acropolis!)
Very highly recommended!
