Nice Villa, you lucked out!
if you're into tech, get your own O2/He Analyzers too. nothing in KSA is consistant
have you checked out the "Cable Wreck" yet? nice deep freediving there, light current, and some of the biggest tuna I have ever seen. the odd Tiger too, so keep eyes peeled. Couple other nice wrecks a short steam out of Jeddah. Viz is dependant on location, some good, some crap. if you can spare time in the winter check out the Farasan Banks for some world class diving.
Shoot me a PM if you ever get over to the East Side, Have some good Canadian Buddies in Ras Tanura that can show you around. don't bring your dive gear, everything on that side sucks compared to where you are
