The 3 bed is a penthouse so will be a lot more expensive, just look at the difference between them. Why somebody would even consider 325k on an apartment is beyond me, you can buy a 4/5 bed detached house in a very good area for that kind of money. What you have to remember is that a lot of apartments get bought by investors to let out so your neighbours could change regularly. Caxton Place is a prime example of this.
