Asking for less than similar flats in the area to get established. Five minutes walk to train station, cafes, bars, restaurants, ten minutes to Byers Rd, Botanic Gardens. Access to massive communal terrace. Good sofa bed means 6 can be accommodated.
No smoking except out the window of the main bedroom.
Other than that, nothing that's not common sense, really. Try not to be too loud too late, try not to damage anything and pay for it if you do etc...
