Nada's place is very clean and has all the amenities required for two people. It is located in a great area, far enough to have a quite night's sleep and an unrestricted view of the Acropolis and the great three mountains Hymettus, Parnitha and Aigaleo as well as Filoppapos Hill, and close enough to walk to Plaka (approximately 35 minutes on foot - less with public transport). The communication with Nada is very consistent and she will help you with your every need.
I highly recommend Nada, you will very much enjoy your stay there!
