Great! Glad to be of help.
A few things to note:
Oxford is spoken of as a ‘small’ city - but in terms of population it’s vast, which means you won’t get a proper idea of the breadth or depth of residential options / areas on a brief visit. You can walk 45 minutes from Carfax in any direction and find yourself in places that seem on another planet to yesterday’s walk.
The press of population in the city centre can be … trying. Even for people from London or other cities. But as a resident you really don’t have to confront St Aldate’s or Cowley Road every day, and you find ways of navigating the city, on foot or bike, that avoid the worst of fifty million tourists in a relatively tiny area.
The universities provide endless entertainment even if you have no formal connection to them. There are a million ways to find yourself attending talks, seminars, conferences, exhibitions, with world famous presenters, for free, as a ‘member of the public’.
And there are probably enough theatres, galleries, museums, concert venues, churches, mosques, to satisfy most of one’s intellectual and spiritual needs.
Being so busy it also feels safe. Teens and young adults and anyone else can leave a cinema or cocktail bar late at night and walk or take the bus home without much worry beyond reasonable alertness.
So, assuming you find the right schools, it could be a superb place to bring up a family.
