Double room, two rooms or small apartment

Hallo everyone,
we are Antonio and Paolo, two aerospace engineers students at their last master year in Italy. We are joining an internship at a company in harburg untillthe first week of august. We have 25 and 26 years old, we are tidy and willing to other cultures and people. We don't have particular request, just a double room or two separeted rooms. We speak english, a little bit of spanish, unfortunately not german but we'll sure learn the basics. Our budget allow us to look for an accomodation at the most for 700€(per month).
For any question please don't esitate to contact me.

Kind regards,
Antonio & Paolo
