Hostels in Tel Aviv
Hi
I think you will experience TLV differently if you stay the night and it is worth it as nightlife in TLV is much more interesting that in Haifa. I know of a few central hostels; I heard that Hayarkon 48 is the best but there are others just check on the accomodation page of Tel Aviv 4 Fun where you can see a list with adresses and telephone numbers

Wish you a pleasant visit to Israel
