CasaBook is a multilingual digital guidebook tool for Airbnb and short-stay hosts that replaces PDFs and printed binders with a mobile web page in English, Spanish, and German. It is built in 20 to 30 minutes, shared as a single link, with no app for the guest to install.
A polished mobile guide your guests will screenshot and remember — not delete.
Build it once. Reuse for every stay. Edit in seconds when the wifi password changes.
Write once in English, Spanish, or German. AI handles the rest. Guests pick their language.
PDFs were never built for phones. Guests pinch-zoom through a document designed for A4, search for the Wi-Fi password, and give up when the text is in the wrong language. Every time a host changes the lockbox code or a local restaurant closes, the PDF goes stale and must be re-exported, re-named, and re-attached to every booking thread. For a host with even three or four rentals, that quickly becomes hours of admin every week and a real source of one-star reviews. A live web guidebook removes the file-management problem entirely.
Travellers arriving at a rental do not want to install a new app, create yet another account, or hunt through email attachments. They want one tap from the booking message to the door code. A mobile-first web guidebook loads instantly, works on any phone, and remembers nothing about the guest (no signup, no tracking, no permission prompts). That low friction is also why hosts see far higher read-through on a web guidebook than on a PDF: the cost of opening the page is essentially zero.
Short-stay rentals in Spain, Portugal, Italy, France, and Greece host a guest mix dominated by English, Spanish, and German speakers. A single-language guidebook leaves two-thirds of those guests guessing. Multilingual support is not a nice-to-have for EU hosts. It is the difference between a guest understanding the rubbish-collection days and the host getting a complaint email on Sunday morning. Built-in EN/ES/DE removes the translation work the host would otherwise have to repeat for every booking.
The host writes the guidebook once in their own language. CasaBook then generates English, Spanish, and German versions using AI translation, and exposes every string for the host to review and tweak before publishing. Updates re-translate only the changed paragraphs, so corrections to a single Wi-Fi password do not regenerate the whole guidebook. The host always sees and approves the final text. AI is the first-draft engine, not the editor.
The guidebooks guests open and re-open share a few traits: they answer the obvious questions first (door code, Wi-Fi, check-out time), they read well on a phone in portrait, they are in the guest's own language, and they include a handful of local recommendations the host genuinely likes rather than a copy-paste of the city's tourist board. CasaBook is structured around those defaults, so a new host's first guidebook reaches that quality bar without design work.
A digital guidebook is a mobile-friendly web page that replaces the printed binder or PDF in a short-stay rental. Guests open a link and get check-in instructions, Wi-Fi, house rules, and local recommendations on their phone. CasaBook builds these guidebooks in English, Spanish, and German with no app for the guest to install.
Sign up, add your property details once in your own language, and CasaBook translates the content into English, Spanish, and German with AI. You can review and edit each translation, then share a single link or QR code with every booking. Guests pick their language on arrival.
CasaBook ships with English, Spanish, and German built in, covering the dominant guest languages for short-stay rentals in Spain, Portugal, Italy, and most of Mediterranean Europe. Guests switch language with one tap on the guidebook.
CasaBook costs 99€ as a one-time payment for a single property guidebook, or 19€ per month for unlimited properties on the same account. Both plans include all three languages, unlimited guests, and AI-assisted translation. There is no per-guest fee.
Yes. CasaBook guidebooks open as a normal web page on any phone or tablet, with no App Store, no login, and no QR-code scanner app required. Guests just tap the link in their welcome message and the guidebook loads instantly.
A PDF is static, single-language, and painful to read on a phone. CasaBook is a live web page, so guests get one link that always shows the latest information in their language. Updates to Wi-Fi, check-in, or local tips appear instantly without resending files.
Most hosts publish their first CasaBook guidebook in 20 to 30 minutes. You fill in property details once, AI translation handles English, Spanish, and German, and you share the link. There is no design work to do.
Yes. CasaBook works for any short-stay rental worldwide. It is built around the EN/ES/DE language mix that dominates Mediterranean Europe, so it is especially useful for hosts in Spain, Portugal, Italy, France, Greece, and across the EU.
