Vietnamese contact for visit around Christmas? (Paris)

Hey there! I'm not sure if this thread is supposed to go here, but I'd be happy if you could help me!
My family and me are planning on coming to Paris, and it would be nice if there was a person who speaks Vietnamese and knows their way around the city to have a nice chat with and ask a couple of questions via mail, before we actually get there. In return, I can help you out if you ever happen to come to Berlin.
Other than that, I'd also appreciate some insider tips on must-see places in Paris.
Thanks in advance!
