 Monitor Idealista Rental Prices and Send Slack Alerts

Who is this for?

Apartment hunters, property managers, and relocation consultants who want instant Slack notifications when new rental listings appear on Idealista matching their exact criteria.

What this workflow does

Never miss a new rental listing on Idealista again. This workflow runs every 6 hours, scrapes the latest rental listings matching your exact criteria, detects genuinely new listings you haven't seen before, and sends Slack alerts with price, size, location, and a direct link.

This workflow uses the n8n-nodes-idealista-scraper community node and requires a self-hosted n8n instance.

How it works

1. The Schedule Trigger fires every 6 hours 2. The Idealista Scraper fetches latest rentals via API-based extraction (never breaks unlike screen scrapers) 3. The Code node compares results against previously seen listings using n8n's workflow static data 4. Only genuinely new listings pass through -- duplicates are automatically filtered out 5. Each new listing is sent as a rich Slack message and logged to Google Sheets
