Patras

In the afternoon it is still hot in Patras. but because the sun comes up about 30 minutes later, the mornings are cooler than in July.
I am going back to the USA, flying on Sep 01 from Athens to Frankfurt and from there with Condor to Phoenix. 
From Phoenix with a rental car to Flagstaff.

Why?
The original rental period ends on October 01, with an optional of renewal for me or the owner.
Things changed: The apartment in Patras, where the owner was living, has been sold and he wants to come back to the house as per Sep 01.
