Aparment/small studio search

Hi everyone, my name is Héctor and I’m a 25 years old Spanish engineer looking for an apartment to start living during the last days of September/begining of October since I've found a new job in Hamburg. I'm a social and friendly person, open-minded and respectful. I've just finished uni so for me the perfect place would be an apartment with senior students or young proffesionals, but I'm open to other posibillities. Also I'd like to live with German people to try to learn the lenguage and integrate asap, as you can see right now my German knowledge is low...
I'm looking for an apartment to have a first contact with the city in a nice atmosphere with respectful and clean people, whom like to watch a movie or cook something together from time to time or enjoy a glass of wine. I like doing sports although I'm not an athlete, listening to music and reading. Since I have some alergy issues, the place I'm looking for should be pet free (cats and dogs only, no problems with no-fur animals, :D) . If you think you have something to offer or you'd like to know something else about myself, don't hesitate to contact me!
