If u were coming to live here for like 3-6 months then you’d have a problem fitting it all into one suitcase, but just for a month – it’s cheaper to buy takeouts and plasticware than to buy all the stuff or bring it with you.
Essentials are clothes for a week or two (i hope you’ll have a washing machine), anti-perspirants (still havent discovered where to buy that here) and i cant think of much else that’s ESSENTIAL that cant be bought in israel….
if you’re subletting u should be able to use their bedding and towels etc
