I would love a quiet ensuite room within a house, quiet and friendly housemates. Shared clean living room and kitchen. Preferably non-smokers, professionals or post-graduate students. No gender or race preference. I would also prefer a house with no more than 4 housemates (if possible). Very close to the underground or overground or bus stops (I need easy access to work close to Roundwood Avenue Stockley Park Uxbridge, Middlesex UB11 1AF) If the house is close to supermarkets or shops, that'll be great.
I am a medical professional, I am friendly, respectful and would be a good stress-free housemate
