Very nice, good-sized single room, own bathroom

Very nice, clean, good-sized single room with own private bathroom in a lovely, modern house in a quiet cul-de-sac near to both Chichester town centre and countryside.
The room (10ftx10ft) and own bathroom (9ftx8ft) are in an extended part of the house, on the ground floor and so offers a good degree of privacy.
The house is situated within a 10min walk to city centre, 10/15min walk to both Chichester Uni and College, 15/20min walk to St Richards Hospital (5min by car), 10min drive to Rolls Royce (also easily cyclable).
The house has a long, private driveway so safe, off-road parking is not a problem. There is also a garage for bikes, etc.
Large, communal kitchen/dining room and gardens and patio.
I work in education and the arts. My recently graduated son and girlfriend are temporarily living in the same house but have their own space upstairs. They are both very quiet and respectful! We are looking for someone friendly and trustworthy but who likes their own space and privacy and who appreciates living in a quiet and peaceful environment.
I'm looking for someone Mon-Fri. The room would remain yours at weekends and I can provide regular clean bed linen and towels for convenience. If you are also intending to stay long-term that would be great!
