Medium Term Accommodation Wanted By Downsizer

I have just sold the rural home in which I have lived for 30 years ( when not away working during the University term time) or travelling for work or pleasure. I am in the process of downsizing and return to city living after 35 years living in the wilds. I will eventually buy another property but I want to take my time to look around hence, having used this site successfully in the past whilst working away, I find myself here.
I am a sociable retired University Professor and lawyer. I would like a house share with one or two other mature adults or family who are the homeowners. Jesmond or decent safe parts of Gosforth preferred. Ponteland or Alnwick too. Proximity to public transport and possibly a parking space or permit for my car are important as when I am not house hunting I intend to be away a fair bit. I am friendly, easy going yet respectful of others' privacy and need for space. Very happy to babysit or dog sitting and walk! I have a slight cat allergy but a resident cat is not a problem if I can give it a wide berth. Bills and broadband inclusive rent preferred and this would suit a single parent/single person/divorcee/widow(er) or empty nester keen to maximise spare room income and have a non-intrusive but sociable lodger. Mature, sensible and grounded professionals preferred please. Live in landlords only please and NO AGENTS or HMOs and PLEASE don't reply if you are outside of my specific target area.
