Flat for a couple staying in Göttingen this summer

Hallo!

I'm a PhD student from Spain, and I will be doing a research stage in the University of Göttingen during this summer. My boyfriend will come with me and join the International Summer German Course in the same University. We will need accommodation for one month and a half, as we're arriving the 17th of July and leaving at the end of August. We already know and love the city, as we came last year too. We have friends there that can visit the possible flats. We will also buy bikes, so, even if it would be better to stay near the University (Nord or Central Campus), it will be fine if with a little ride you can reach them. We are quiet and respectful and we do not smoke or bring any pet with us. If you are thinking on renting your room just for August, maybe it's better to arrange the rent with us and then get it rented for a little bit more! :)
