Hi,
For the location you can check it out on maps.google.com and search for Zouk Mosbeh, Lebanon.
This may work.
So you can see it is outside Beirut, at a rough estimate 20 minutes north on the coastal motorway to the tunnel Nahr el Kalb, then slightly inland. Travelling to Beirut and back during rush hour on this road can be extremely slow. Are you thinking of working or living there - or both?
I don't know the town itself, but have been through the area several times heading to Faqra, Jeita or Sheile and it seems safe.
Maybe someone who knows it better can provide some detail on what it is like.
