Furnished Flat/Apartment with Private Kitchen and Bathroom at Haar, Munich

I will be joing as an employee at a company in Haar, Munich. Before this, I was working as a reseach employee at Max Planck Institute in Halle (Saale), Germany and stayed there at an apartment/flat for three years having a very good relationship with the landlord. I have been to different countries for research and stayed at several houses/flats as a tenant for short/long term. Currently I have decided to move to Haar because of my new job. So, I am looking for a one-room furnished flat with an equipped kitchen. I will be very happy to stay at such room as a tenant so that I can pursue my work peacefully. I know three languages including English and I am learning German language to enhance my language skills. I also have a letter of recommendation from my new employer/company (if necessary) for convenience.
