A couple looking for a 1-room or a 2-room apartment in Berlin for 2 months (May 1-June 30)

I am working for a Swedish company and have been relocated to Germany to open up a new office and I am therefore looking for a place to stay for a year. My husband is working for a Swedish company called Motatos which has an office in Berlin where he will be working during this period so everything is all set - we just need a place to stay.

We are a couple in our 30s which means that we are too old to party ;) We are just looking for a cozy apartment that we could call home. We are non-smokers and enjoy cooking and taking long walks in our spare time. We are a very responsible couple and we own an apartment in Sweden that we will rent out ourselves so we know how important it is to find a good tenant that you can trust and who will take care of the apartment as if it is their own.

We have found an apartment in Mitte that we will be renting from January to May so we are now looking for an apartment to rent for two months- from May 1 to June 30.
