Dear Sir or Madam,
My name is Lisa, I am a medical student from Germany. I will do an internship at Wolfson Molecular Imaging Centre from February 10th to March 10th and looking for an accommodation for this period of time. Please let me know if yours would be available. I am friendly and rather tidy.
I am looking forward to hearing from you, my e-mail address is firstname.lastname@example.org.
