Looking for a flat to rent for 5 months in Koln

Hello/Hallo/Guten tag :)
i am a 20 year old male university student from Indonesia currently studying in Soest and soon i will be conducting a mandatory internship in Koln.

I am currently looking for a place to stay for 5 months (From 1st of march 2018 until july 2018) in a area near Mulheim or somewhere near the left side of the river.

my budget is about 500-600~ eur a month for rent. i am looking for a place with complete utilities such as internet, hot water, heater. also looking for a Furnished place which includes necessary home appliances; washing machine, kitchen area, etc
i do not need a parking space as i do not own a car, but i prefer if the location of the flat is easily accessible through public transportation such as buses or trains

if you have a place you're willing to rent to me or need any additional information feel free to contact me through my email : MAIL or my German mobile number: ----/------- . Feel free to WhatsApp me as well through this number: (+62)816954999

unfortunately i am not good in speaking German, but however i am confident in my English and Bahasa Indonesia skills.

if you would like me to visit your flat for me to look around id be happy to come and i am available most days. but it would take me about 2-3 hours to travel from Soest to Koln

Koln is a beautiful city and id be glad if you could help me out in getting a place to stay. i visited the karneval a week ago and it was fun!

Vielen Dank!
