low cost bed for 3 months

Hello, I am an italian student coming to Tel Aviv in April for a internship at the italian chamber of commerce. i speak fluently english and spanish, beside italian. i am a fun and very chill person, but considering that i'll be working from 8am 5 days a week i would like a quiet house during working days. moreover, as the internship is not paid, i'm looking for a cheap accomodation. anything could work, really, so let me know. see you soon ;)
