Moving to Plymouth, what are the nicer areas that don't cost a fortune?

Me and my partner are looking to move back to Devon, and Plymouth seems like the best place for us (only partially because I want to see Argyle play), we are looking at cheap-ish areas which are safe and pleasant, preferably central as we'd both be working near the centre of town and don't drive. We have been looking at Stoke and near Mutley, but also found a cheap place in Devonport near Mount Wise park, but I've heard some bad things about that area. Could anyone who lives there/lived there recently let us know where we'd be best to look? (For context Ill_temperature2592 is my partner making silly comments because I won't let her buy a tiny flat in the southern part of Devonport)
