1) Any recommendations as to which area/hotel I should stay in?
2) The nearest code I could find for Porte Maillot is the Concorde Lafeyette 75017. Does this mean Porte Maillot is in 17 rue arrondissement? Some hotel bookings site uses arrondissmont.
3) What time does the earliest metro/rer starts and if it's safe to be walking in the early hours on foot to get to Porte Maillot. (Assuming I'm unable to find nearby hotel due to full occupancy or it's out of my price range)
Thanks in advance for any advice.
