The apartment is situated just outside the main bar and restaurant area, and is within walking distance to the major archaeological sites so it's extremely convenient (I didn't even take the metro to get around during my 4-day stay, only once to Piraeus), so definitely very convenient! As it's close to the main entertainment district, it can be a bit noisy in the evening, but it didn't bother me as I am not a light sleeper. One bonus point is that the TV connects to YouTube and BBC World news, so it's not short of in-room entertainment. Couple of things to note - some descriptions might not be accurate (minor stuff, e.g. complimentary bottles of water), and more importantly, luggage storage is unlikely to be available as it is run by a 'company'. The latter has deterred me from booking the apartment on my return to Athens, but otherwise, I'd stay there again.
