Spanish guy going to Israel in January

Hello bloggers,
IŽm going through the forum and IŽm already finding loads of usefull information so iŽll just ask what i need
IŽm off to Israel(Tel Aviv) in January, IŽd like to stay for about 3 months, and I Žd like to know if someone could tell me what is the cost of living in Israel such as groceries, eating out and daily things, and also as I am planning to stay for 3 months I was wondering what is my best bet about accommodation for 3 months as I donŽt wanna make it too expensive for myselve, what kind of rentals there is and so on, and how do i find them, I guess i wouldnŽt mind sharing a place or something,
many thanx in advance,
fk
