Yes a taxi or Über would work. A taxi will cost around 30€ plus 4 or 7€ for the reservation.
If you are near Bagneux RER-B station then you can get to Gare de Lyon by changing at Chatelet and then taking the RER-A.
Thanks for the concern. I am getting economical accommodation through Airbnb (near about 25 euros / night). In main Paris the charges are more. I can use that extra amount in travelling and fooding.
Can you suggest any accommodation at Paris or near Paris Gare de Lyon within this budget? I will be having my 9 year old kid with me.
Thanks dg2006 for your reply.
Is Uber easily available at that early morning of 6 am?
And the place is what he called "Metro line 4 ,station Montrouge, and then bus 128, station Jean Naudin".
Do you think taking Metro can be possible from this place at that early morning at 6.
Yes, the Metro will be running at that time and it might take 25-35 minutes (depending on connections, you finding them, etc.)
There are a couple of options if you are close to Metro line 4, use the official planner below. Put in the exact dates and address (or just use the Metro station as a staring point). You should get a good estimate of travel time..
But you should consider how many suitcases, hauling them up and down steps etc. when choosing between taxi/uber and transit system.Edited: 22 September 2017, 18:57
