The location of this apartment is excellent. It is very close to Syntagma Square, which means that connectivity with airport (X95 bus) and other parts of Athens is very convenient. There are large number of restaurants, mini-market and shops right next to the apartment. Acropolis, Olympieion, Ancient Agora, Roman Agora, etc, can be reached by brisk walk of 20-30 minutes. However, the description of the apartment as being "next to Acropolis" is inaccurate.
The apartment itself is decent and reasonably well furnished. The queen size bed is comfortable with good bed linen, pillows and blanket. The big sofa is also very useful. The balcony is very nice but we did not use it as it was a little cold outside. Bathroom is a bit cramped and paint is peeling off the ceiling. Some wooden cabinets in the cooking area (there is no separate kitchen as such) are not properly painted. The building in which this apartment is located appears to be old and not too well maintained (the lobby, lift and corridors look a bit shabby).
There is a split air-conditioner which can cool as well as heat. We used only the heating mode and found it to be quite effective. WiFi worked very well.
On the whole, my wife and I had a pleasant stay for 3 nights.
