student accommodation

My name is Akash Palh and I'm going to start my postgraduate studies (MSc Cognitive Systems) at the University of Potsdam, Potsdam, Germany from the 16th of October, 2023. I will arrive in Potsdam in the first week of October.
A little bit about myself: I am from Karachi, Pakistan. I am 30 years old and I am a very active person. I love to keep myself fit and strong through a variety of activities like working out and playing football. I am an outgoing and socially active guy. I do not shy away from social interactions. I am a law-abiding citizen and believe in equality and harmony. From 2015 to 2021 I lived in Turin, Italy. During my stay there, I had first-hand experience of the European lifestyle, which accustomed me to the socio-cultural values of an open-minded Europe. I love to travel and I'm always ready for new adventures.
I'm looking for long term accommodation (Shared) with registration, ideally in Potsdam. Living in Berlin is my 2nd choice. Looking for guidance and help. I am ready to start the contract from 1st October.
Any payment is conditional to a prior physical visit.
Budget: 450€ max
