About twenty minutes ago some noise started happening - like an air conditioner noise, only I don't have the heat or the air on. It's really loud. I called the desk guy and he came and heard it - he doesn't have a clew. He tried to tell me it was the fan noise from the building's air conditioner, which you can hear in the hallway. It's not that at all - I told him I've been here since Wednesday and this is the first time I've heard the noise. He offered to change my room but, you know, it's two in the bloody morning. However, if I can't sleep I will have to change because it's really annoying me.
