Looking for 1 room flat | long term | working professional

Hello there!
I moved to Munich on 1st of May 2019 for work, I work as a digital expert in an international company that I have been with since 3 years. I was in Australia for 1 year, and now I'm back, therefore, I am searching for 1 room flat in a central location in Munich starting 1st of June, so I could reach my work easily with the public transport as well as enjoy the city life.

Note: I'm looking for long term period. I am currently living in Westendstraße in a temporary apartment, I'd be happy to meet up in person if you have something for me :).

A little about me:
- I am an organised person, who spends a lot of time at work (including frequent traveling).
- At home, I'd spend most of my time reading, learning over the internet or enjoying relaxing time after a long day at work cooking a nice meal and watching a good movie.
- I don't smoke, don't have a pet and don't play any instruments.
- I lived in Germany before for a short period, so I speak some German (ofc. planning to learn more).

Thanks a lot for your time in advance.
