The hallway, your room, the kitchen and the bathroom (which also houses the toilet) are yours to use (though for some of them you'll have to share). To make it short, the only room where you are not welcome is my flatmate's.
You can call me or e-mail me anytime. My flatmate, Nepheli, will answer your most pressing questions.
If you need a drying rack or an iron for your clothes, please ask my flatmate to provide you with them (she's usually busy so better do so a day prior to your need).
You can smoke in the room but please do air it afterwords and if you want to smoke in a common area, please ask my flatmate, as a courtesy, if she's ok with it and air afterwords.
