23 and 22 year old couple from Spain, looking for accommodation in Riga

It's me and my 23-year-old boyfriend. We both have been given scholarships to spend a few months studying and doing an internship in Riga, so we need accommodation until February. We are very calm, and we don´t really enjoy parties at home. We don´t know exactly when we´ll be arriving, as we are still waiting for news from our schools, but it will probably be around the second half of July. We´re looking for either an apartment or a studio for two.
