Bournemouth is a bit of a sprawling mass. The down side of it is, it's a mecca for stag and hen dos, the town is best avoided on Fridays and Saturdays when it all looks a bit feral. However, it has great beaches and so many lovely places on the doorstep, The New Forest, The Isle of Purbeck, Canford Cliffs, the unaffordable Sandbanks. For a quieter pace Christchurch is right next door, very pretty with an older demographic and further up the coast is Lymington, in between is a town called Highcliffe which is probably cheaper than Bournemouth itself, but possibly not so many flats more houses. Lymington is gorgeous, the high street is Georgian and as Nan Kate says slopes a bit, but only at the end which leads down to the quay. I don't actually live there but we have a time share so go down once a year. I think you should check on Right Move as to affordability. There are a mass of properties in the greater Bournemouth area, particularly flats, some of it's suburbs are definitely less expensive, Boscombe, Pokesdown, Littledown than say Canford Cliffs. Bournemouth also merges with Poole which may be a little cheaper.
