We could hardly be happier with our stay here. The apartment is fantastic and very well located for sight-seeing around Athens. The view is gorgeous, the furniture is comfy and the kitchen and bathroom are clean and functional. Tanasi and his nephew (who checked us in) were both incredibly helpful and responsive throughout the trip.
One note, there is no door between the bedroom and living room with additional futon (just a screen) - so there's not a great deal of privacy or noise-canceling options.
