Accomodation for 2 students offered from February 2018 on

We are two Biomedical Engineering students who are looking for two roommates. The thing is that we are staying in Madrid from September to February, but we haven't found an apartment rentable for this specific amount of time. Therefore, we are looking for two students who would be interested in renting with us an apartment for a year and then live in it from february to june (we would not be there by that time). That way the rent would be cheaper for the 4 of us and it would be much easier to find accommodation. Thank you very much.
