Rotterdam-room or studio for 6 months (01.08.17-01.02.18) with registration possible

I am a 28 year old Swiss graduated food technology engineer looking for a place to stay during my internship at Unilever. I am looking for a furnished room or studio with possible registration for 6 months starting from the 5th of August. I have lived and studied abroad for a while now, usually sharing flats with other students or young professionals. I'm friendly, easygoing and tidy. I speak French, Spanish ,German and English. I am currently living at the student hotel of Rotterdam until the beginning of August, and could be available for a meeting or a visit after work. I look forward to hearing from you!
