Looking for a room

Looking for either spacious double or average size room if additional storage space is available (quite a bit of possessions, current move wasn't planned). As far as furnishing, all I really need is a bedframe.
Preferably all costs (bills, tax, WiFi) included in rent.
Tidy, friendly although somehow introverted.
Currently finishing postgraduate degree, soon intend to seek work at a hospital therefore Marston/Headington area of Oxford preferred with easy access to buses as I don't drive.
