I've lived in Aberdeen for over forty years. I use a private dentist and doctor as the NHS is on its knees. I've not been able to see a GP for two years, you get a practice nurse or GP's assistant instead. My physio assessment was even done by phone. Exercises were recommended even though I had asked for an MRI. In the end I went private, had the MRI within and results in less than a week, and I had a complex tear. Other medical practices may be different. Even the private hospital has waiting lists for some things.
The shopping is dire, and the city centre is in a poor state. I hate to say it, but I shop online a lot.
It's cold and winter days are very short. We recently had a run of over twenty days without any sunshine and I hardly noticed. Today was 7C with gusts.
That said, I love where I live, it's rural, with no buses, but I don't mind having to drive everywhere. The city centre parking however, is the most expensive in Scotland.
Housing is ok, but be careful where you live, lots of new builds with spotty social issue problems to do with bored school kids.
Aberdeen isn't exactly known for its art and culture scene and decent restaurants aren't cheap. Dundee's better.
I guess what I'm saying is to move to Aberdeen you will need to have £££ to get out regularly. Both trains and flights are not cheap.
