[SEEKING] Short term rental needed June 23 to July 1st (8 days)

Looking for a room from June 23 to July 1st. I'm a Brazilian CS Major Student attending Stanford for the summer session. My housing options are only available on July 1st, but I'll arrive in the US June 23, therefore the need for this short term accommodation. I don't mind sharing bathrooms! My top budget is $50 a night.
