Urgent: Exchange PhD student looking for a Flat or Room in Frankfurt for 2.5 months

Hi I'm Marco (26M)! I am a Ph.D. student from Italy, doing research on Cognitive Developmental Robotics.
I will carry out a research exchange period at the Frankfurt Institute of Advanced Studies from February 15th 2025 to May 3rd 2025. I am looking for either a flat or a room in a shared flat for that period: however, given the weird time frame, I am also open to shorter monthly periods (1st February - 30th April), and I will arrange some other accommodations for the remaining days.
Most of the time during my stay I will be at the FIAS, coming home just to cook and rest, so I am not looking for something big or fancy.
I do not smoke, I am respectful, quiet, and like to have my personal space, but I'm all in for some chat or games together if the occasion presents itself!
For any questions or clarifications, or if you need any documentation, do not hesitate to contact me!
