First of all good luck for surviving 3 month with 3 boys on you own! :) If you survived just than you should think about coming here! :) Ok, apart from the joke, I heard that the best school is defenetely DESS. I have a freind whose kids are going to Newton and they are satisfied with it. They learn everything in english, plus additionally arabic and french.
Wait untill your husband gets here to see what accomodation is provided to him. Many times furnished apartmants or villas are avialable. But actually furnitures are not so expensive here, so you can buy most of the things.
