27 years old engineer moving to Berlin on the 1st of May

Hello, my name is Antonio, I'm from Spain and 27 years old. I'm going to move to Berlin on the 1st of May because I'm going to start working in a railway company as an engineer. I've been working in Barcelona as an engineer until the end of March so I can show my last salaries and the work contract with the new company to prove that I have enough money to pay the rent. During this month (April) I'm in Geneva (Switzerland) making a training course for my new job. I'm a quiet and respectful guy, tidy and clean. I speak good English but German not so good yet. If you choose me for the flat I can ensure you that I will take care of it. If you want to know more about me please don't hesitate to ask ;) Thank you for your response in advance :)
