CHECK24 Hotel Reviews Scraper

Scrape verified hotel guest reviews from CHECK24 Hotelvergleich with ratings, detailed feedback, travel dates, and guest information in JSON format.

What You Get

• Complete review texts including positive, neutral, and negative feedback
• Guest ratings on a 1–10 scale per review, plus aggregate category ratings
• Verified stays — all reviews are from confirmed bookers on CHECK24
• Travel metadata — dates, traveler type (family, couple, solo, etc.), room types
• Guest profiles — names (often anonymized), visit counts, locations
• Site-specific fields — season, business trip flag, pet-friendly stay indicator
• Structured JSON ready for analytics, comparison tools, and review aggregation

Key Features

✓ Fast and cheap — HTTP API only (no browser); 390 reviews in ~5 seconds
✓ High volume — Process thousands of hotels via the Apify Scheduler
✓ Date filtering — Extract reviews from specific date ranges (e.g., "summer 2026")
✓ Limit controls — Scrape first N reviews to save costs
✓ Scalable — Batch process multiple hotels per run
✓ Production-ready — Retry logic, proxy support, error handling

What It Does NOT Include

• No owner replies — CHECK24 does not publish hotelier responses (unlike HolidayCheck or Expedia)
• No review photos — Gallery media not exposed in the API
• No per-review category scores — Only hotel-wide aggregate ratings available

This is by design; CHECK24 offers first-party, verified guest reviews that stand alone without management responses.

Use Cases

Review Aggregation & Analysis

Combine CHECK24 reviews with data from HolidayCheck, Expedia, and Zoover for comprehensive multi-source review analytics and sentiment analysis.

Price Intelligence

Cross-reference reviews with booking data to identify review volume trends and guest satisfaction patterns before/after price changes.

Competitor Monitoring

Track review trends across competitor hotels in a region or segment (e.g., 5-star all-inclusives in Turkey).

Review Moderation

Export all reviews in structured format for moderation, compliance, or content management systems.

Research & Reports

Generate data exports for academic research, travel guides, or industry benchmarks.

How It Works

1. Extract hotel ID — Actor parses the CHECK24 hotel URL to find the clusterId.
2. Fetch reviews — Queries the public JSON API (/api-hotel/proxy/portale/cluster/{id}/reviews/list.json).
3. Paginate — Loops through pages (100 reviews per page) until all are fetched or limit is hit.
4. Filter dates — Optionally filters reviews by publication date (client-side).
5. Normalize — Maps CHECK24 field names to standard schema.
6. Output — Pushes each review as JSON to the dataset.

Input Parameters

Hotel URLs (startUrls) — required

CHECK24 hotel URLs in this format:

https://hotel.check24.de/search/{HotelName}-{clusterId}/hotel.html

Query parameters (e.g., ?c9=...) are optional and ignored.

Max Reviews per Hotel

Default: 0 (all reviews). Set to a number (e.g., 50) to limit cost.

Date Range

• Review date from (YYYY-MM-DD) — Scrape only reviews published on/after this date.
• Review date to (YYYY-MM-DD) — Scrape only reviews published on/before this date.

Both are optional; leave blank for no date limit.

Raw Data

If enabled, includes the raw API response payload in each review (raw field) for advanced debugging.

FAQ

Q: Why no owner responses?
A: CHECK24 does not publish hotelier replies. The platform focuses on verified guest reviews. For owner responses, use the HolidayCheck or Zoover actors.

Q: Can I scrape multiple hotels at once?
A: Yes, add multiple URLs to startUrls. Each hotel is crawled sequentially.

Q: How do I filter reviews by date?
A: Use the dateFrom and dateTo input fields (YYYY-MM-DD format). Filtering happens client-side after fetching.

Q: Is it legal to scrape CHECK24?
A: CHECK24's reviews are public and scraped via their public API. Always respect their terms of service and robots.txt. For commercial use, contact CHECK24's business team.

Q: What languages are supported?
A: Reviews are primarily German (CHECK24's main market). The originalLocale field indicates the language of each review.

Q: Do I need a proxy?
A: No. The actor works with datacenter IPs. Residential proxies are optional fallback for future rate-limiting.

Limitations & Notes

• No photos — Review images are not available via the API.
• Aggregate ratings only — Category ratings (room, service, cleanliness) are hotel-level, not per-review.
• Relevance sort — Server only supports sorting by relevance; date-based sorting is client-side.
• German platform — Some fields (seasons, traveler types) are localized to German.
