Aris emailed us detailed instructions to his apartment so we would not get lost. He saved us a temporary parking spot so we could drop off our luggage before returning our rental car to the airport. When our GPS didn't quite get us to the apartment I was able to use his map to walk to the apartment and Aris walked back to the car with me to guide us to his apartment.
The apartment is very clean and a good size for two people. The area was very safe and there are lots of restaurants nearby. It is close enough to walk to all the major sites and close to the metro to get to and from the airport.
Aris provides you with a cellphone to be able to contact him, a map of Athens, and a tablet for browsing the internet.
