We found Ginas apartment very easy to find. Her instructions were very formative. We flew into Athen airport and caught the metro and walked to the apartment. Stopping on the way for a cold drink. The acropolis is around 40minutes on foot but you can easily take a local bus. We left Athens to go to Santarini and caught the Metro to the port. It is around 15minute walk to the metro. We went to the archaeological museum first. They hold your luggage for free while you are inside. This is around 10-15mins from the metro. Really easy to get around using local transport. There is no need to use expensive taxis.
