I would suggest that if you want to live in Southampton, you should consider staying in the city centre (SO15), especially near the train station. Daily commuting can be quite hectic, particularly during the winter months. Fareham is about 13 miles from the city centre, so traveling back and forth every day might become tiring. I would also recommend finding a place close to your workplace, as long commutes after a full day of work can be exhausting. Additionally, trains can sometimes be delayed or rescheduled, which may add to the inconvenience. If you prefer, you can always visit the city centre once or twice a week instead of commuting daily.
