2 bed room apartment wanted in Berlin from 1st week of October, 1100 max rent budget

Dear Sir / Madam,
My name is Dibyajyoti an international student based out of Berlin, I and my partner who is also a student from HTW Berlin both are looking for an apartment with a long-term contract and anmeldung from 1st week of October for at least 6-12 Months.
We are actively looking for offers but have no luck yet, we ask for your help if in case of any possible available apartments in Berlin, as our classes are about to start and we are in need of an apartment.
About Us:
We are both 30 year old international student, been together for over 10 years, we are very private people and we understand and respect others privacy as well, we limit our social gathering outside, so no parties or noises from our side, we like to remain neat and clean on daily basis and we believe and implement sustainability in our live as well.
Apart from this we are fun people to hang out when we meet people in general.
About finances:
For financing, we have our financial block account from which we will be able to manage the monthly rent apart from that as international students we are allowed to work 120 days to earn a little extra, meanwhile, I am going to start my internship in a software company in Berlin, so from the financial end we are totally sorted out.
Hope this information is relevant for evaluation.
We seek your help for finding us an apartment as soon as possible.
I am looking forward to hearing from you.

Thanks & Regards,
Dibyajyoti
