Location note: this is tagged Sydney, Australia, but my property search was for a studio around Porto, Portugal. Idealista gave me useful search coverage, yet duplicate listings, stale availability and inconsistent floor-area data made comparison harder than expected. The closing-cost information was the most valuable feature for me. The biggest gaps were clear listing-freshness signals and an obvious next step after finding a property. How does that compare with the mobile experience and what happens after contacting an advertiser?
