I lived in Norwich for 6 years but have moved out to a village now. It's a wonderful place to live.
Tomblands is lovely but very busy, no parking, lots of students and tourists up and down your road, probably photographing your house, shoppers wandering past and a surprising amount of crime because you're in a city centre, a stone's throw from the main clubbing street in the city.
It's very pretty though. Part of the film Stardust was filmed down there. Norwich is lovely but Tomblands isn't a place for downsizing to simplicity.
