I'd go with the 'researcher' label! My landlady refused to take undergraduates as her accommodation is all quite new, but she will take masters or PhD students, as long as they seem 'okay'. On a related note, I do get frustrated with my local GP surgery, because every time I ring up and ask them for an appointment they ask if I'm a student. Apparently students aren't allowed to take the early morning appointments since they are viewed to have all day to go to the doctor, obviously with nothing more important to do. I have tried explaining that I am a PhD student and that I therefore must be in the office between 9-5pm, but that only gets me anywhere with one of the receptionists! Grrrr! Best, KB
