Employee in max planck institute, looks for a flat starts from May,

I am single male, no kids, full time employed by max planck institute for biophysical chemistry;
looking for an apartment with 1 or 2 rooms, which is close/well connected by bus to street ‘Am Faßberg’ and the other parts of the town; rental lower than 600 Euro would be fine.
A starting date at the beginning of May would be perfect
See below for a more detailed description:

I am a foreigner employed by the Max-Planck Institute for Biophysical Chemistry in Goettingen . Whether it is furnished or not is not important, but basic kitchen fixtures such as stove and fridge is a great plus for me. Generally, I cook several times each week. Quite and clean are mandatory. I am an open minded and easy going person, one disadvantage is I do not speak German, so the best way of communication for me is by English. A one room apartment is perfect, but 2 room flat is also fine if I am allowed to look for a roommate to share the other room. You are welcome to contact me by email , I just arrived German and do not have a German phone number yet, but in case you would like to call, you can reach me by +1-5879698509 .
