Once I managed to get hold of the pre-arrival details (essential, as I was arriving at 0400hrs), and mastered the key safes, it was a great property. VERY reasonably priced - just me in an apartment that could sleep 6, at 1/6 price top of the range Marriott property in town.
Clean throughout on arrival, air con and wifi worked instantly and the TV had been left on BBC News when I turned it on (I'm British).
Bed was comfortable and linen crisp and fresh.
Only water left in fridge for arrival (tap water is marked as drinkable) but there's a supermarket 2 blocks away for all basics such as milk, teabags and the like. Every other shop in Athens seems to be an artisanal coffee shop, and there's a splendid (tastty and friendly)Souvlaki resto at the top of the incline, 50m away.I was in Athens for the mega Posidonia conference at the airport and associated parties, and taxis were easily and quickly obtained used the FreeNow app that I use in Spain.
The airport bus stops 25m away (though no use for me arriving and departing at stupid hours during the night).
Excellent stay and would return here if visiting Athens again
