The apartment was spotless and quite bigger than we expected from the pictures. The bed was large and a bit stiff (which we didn't mind). The fridge could've been larger and the kitchen could've used more pots (a smaller one for eggs perhaps), but we didn't really come to Greece to cook so we didn't mind terribly.
There is a bus station right outside the entrance and a metro station some 10 minutes away, there's plenty of food options nearby as well as a mini-mart which is all very nice.
Anastasia and her husband were warm and welcoming, they showed us around the place and gave us some tips on what to do in Athens.
