I'll be there Wednesday Thursday what I heard that it's not comfortable to go dressed with a yarmulka and beard and פאות so u got to dress little different also don't go out at night
If really unsafe to go out at night -DO NOT EVEN GO!--
I never go anyplace that I feel threatened or know I am unwanted
Though I am not so sure that going out is not safe in Paris ( any on Dans ever encounter any problems that do not plague other cities ?)
Paris is a lovely city ---but not if one is scared -worried or frightened
