I am getting nervous. I will be alone in Opera/Montmarte area on Rue del'Agent Bailly. My Lufthansa flight leaves at 12:05 p.m.(noon) I would like to be to the airport by 10:a.m. I think it is terminal 1. I don't really want to pay for a taxi. What would be the very SIMPLEST way for me to get to airport? I do not speak or read French, and of course it is very important to get to the airport on time. I will have no phone and no internet after I leave the apartment. This will be on Monday June 16. Thanks in advance!
