Looking for an apartment/shared flat for an internship

I'm looking for an apartment/shared flat for max. 7000Kr. per month.
I’ll arrive in Stockholm on August 28 and will do an internship for 4 months from September on by the artist Anton Alvarez in his studio in Gustavsberg, where he mainly works with ceramics and bronze sculptures.
I study fashion design and will be finished with my master's thesis next month, in which I mainly worked with ceramics and textile objects. During the master course I got to know more and more about ceramics and sculpturing, so the internship offers me the perfect opportunity to develop myself in the field.
I live in Trier in a shared flat and also did in the other cities I lived so far. The most important thing for me is open communication and consideration for each other.
Besides my studies I work with children and give creative workshops in elementary schools and work in a ceramics store. From time to time I do pottery on the wheel and then sell the things.
I’m open to activities and would like to go climbing and hiking, generally explore the nature around and also get to know the art and culture scene there.
It would be great to find a place which is not too far from Gustavsberg and which is close to public transport.
