Simple no-frills script to scrape immoweb.be - nothing fancy, suggestions are more than welcome.

• Currently floor area and number of bedrooms as search criteria (min_floor_area, max_floor_area, min_num_bedrooms, max_num_bedrooms). Could easily adjust the URL to accommodate extra filters.
• max_pages sets maximum number of result pages that will be scraped for every search. If in doubt, choose a high number

The municipality name in the URL (eg .../st-gilles/...) does not seem to matter - what matters is the postcode (postal code). As long as the postcode is set appropriately, the URL will return the right results.

Finally, made this for personal use on a limited number of listings - scraped data should not be used for commercial purposes. As always, please be sensible!
