What do you like about it, if you don't mind my asking? I'm moving to Newcastle in August for school, and am looking to get as much info as possible.
I know you didn't ask me, but I'll chime in anyway.

Newcastle is just a generally pretty place---the area around Monument, Grey Street, all the way down to the Quayside, full of beautiful architecture.
Jesmond Dene, especially in the spring and summer.
Sunny weather (at least compared to the West Coast).
It's compact and easy to get around.
The people are friendly---plus, Geordie accents!
Tyneside Cinema and its terrific coffee bar
The Biscuit Factory
You can get to the coast on the Metro in half an hour
Tons of history
Easy to get to Edinburgh
Etc, etc, etc....
I'm sure hjarrett and Jewlz can add more. Newcastle's great though. But windy. Very windy. Buy a birdcage umbrella; a normal umbrella wouldn't last a week (I speak from experience!).
