West I think the whole block is ex-local authority. The daughter of the current owner of the block still lives in the flat that I looked around today (she wasn't in the flat at the time though).
I actually was also in Queen's Crescent today. I'd originally planned to look at a flat there, but the tenants weren't in at the time of my appointment, so the estate agent suggested looking at this property instead. I think that Prince of Wales road seems a bit quieter than Queen's Crescent (from what I've seen of both roads so far in the daytime, so around 5:30/6pm).
I've also looked at the prices of flats on surrounding streets, and they seem to be much, much more expensive (at least £700,000).
