@angledust;
Where are you planning to work, are you living alone or with a family? Are you buying or renting. How would you want to get to work?
Forget about mountain biking locally, it’s just not that good.
Do you plan to use the city centre on a weekend? If so forget it in summer, language schools and tourism dominate the centre on a weekend and make it a pain to get into and out of. Over the 13 or so years I’ve lived in the area of a weekend there used to be 3-5 coaches parked in the lay-by on Barton road, last time I was in the area I counted 21 coaches!
Overall though it’s a lovely city in many ways, good pubs, great annual beer festival, historic colleges, city centre greens spaces. Travel links are ok, roads can be crap at peak times as mentioned above, but just avoid car travel at these times.
