We decided not to deal with the laundry machines in the basement of the Cite, too few machines, too many residents, and not inexpensive. Yesterday, we went to the little place next to the internet cafe on rue Jouy
The man on duty was very helpful and spoke some English. We were able to take a walk during the wash cycle and do a bit of marketing during the dry cycle. It wasn't inexpensive either, but it was stress free. And who needs stress when doing laundry!?
Note the black string bag (filet) and the neatly folded black and gray clothing. Hmmm, whose laundry could this be? ha ha ha
