Really cool site - my only (minor) criticism would be that the sliders for number of bedrooms let you select (approximately) 1.3 bedrooms, etc. Would be nice if they 'snapped' to 1/2/3... Other than that, very useful!
ah ha, 1.3 is actually 1 :D, some people prefer a smooth transition (like me :D), so this will be taken into consideration.
Fair enough, I think it's personal preference like you said. Perhaps being able to choose a range would be good too.. recently I was looking for a 1 or 2 bed.
