Best Guest vs. Guestbook

Best Guest vs. Guestbook: Which Fits Czech Guest Registration and Daily Operations?

How Best Guest and Guestbook compare for guest registration, UbyPort reporting, accommodation tax, and day-to-day apartment operations in the Czech Republic.

Bottom line

Guestbook is a Czech app for running an apartment day to day: check-in with TTLock smart locks, collecting the accommodation tax from guests by card, and a shared cleaning calendar, at 300 CZK per apartment per month. Best Guest is compliance infrastructure built to scale: UbyPort, the House Book and Registration Book, tax calculated per your municipality's rules, check-in in 43 languages, PMS and calendar integrations via iCal, and team roles across multiple properties — priced per completed check-in, not per apartment. If collecting the tax by card is what you need today, Guestbook leads there. Best Guest matches Guestbook on smart locks (TTLock and WeLock) and goes further on compliance depth, foreign guests, integrations, and room to grow.

Best Guest vs. Guestbook at a glance

Both tools are built specifically for Czech hosts, and both automate guest registration and UbyPort reporting. They differ in their center of gravity. Guestbook is an app for running an apartment day to day: the guest registers, pays the tax by card, receives a PIN for the lock, and the cleaner sees when to clean. Best Guest is infrastructure for legal obligations and growth: depth in Czech regulations, check-in in 43 languages, integrations with your booking channels, and tools for a team managing multiple properties.

What Guestbook does well

Guestbook’s public website describes a well-thought-out operational chain: the guest receives a registration link via Airbnb or Booking.com messages, fills in a mobile form, pays the accommodation tax by card, Apple Pay, or Google Pay directly to the host’s account (with a 1% service fee per transaction, min. 5 CZK) — and only then is the PIN for the TTLock smart lock released, auto-revoked after checkout. On top of that: a shared cleaning calendar with departures and guest counts, video instructions via YouTube, direct UbyPort API reporting with delivery-receipt capture, and a 6-year data archive. Pricing is simple: 300 CZK per apartment per month, or 225 CZK per month billed annually.

Where Best Guest specializes

Best Guest goes deep where obligations and operations grow. The check-in form guides guests in 43 languages, not just Czech and English — and incorrectly filled data from foreign guests is the most common source of reporting problems. The accommodation tax is calculated per your specific municipality’s current rate and exemptions, not a generic formula. The House Book and Registration Book are native to the system, with an audit trail. Reservations load from your actual channels via iCal and direct integrations, so nothing is retyped by hand. And once you manage multiple properties or work as a team, you get owner / manager / member / cleaner roles — including a cleaning agenda where the cleaner sees departures and marks the apartment as ready. Pricing follows completed check-ins, not a flat fee per apartment.

How to choose

If you run a few apartments and want to collect the accommodation tax from guests by card and let them in with a TTLock PIN today, Guestbook is a very complete operations package — just plan around a form available only in Czech and English and a flat fee per apartment. If you host foreign guests from many countries, need PMS or channel-manager integrations, manage multiple properties with a team, or want certainty in compliance depth (municipal rates, exemptions, the House Book, an audit trail), Best Guest is the more specialized choice — noting that card collection of the tax is still on our roadmap.

Frequently Asked Questions

Does Guestbook handle UbyPort reporting?

Yes — Guestbook's website describes direct UbyPort API submission including automatic delivery-receipt capture, and a 6-year data archive. The difference isn't whether UbyPort works, but what surrounds it: Best Guest adds check-in in 43 languages, a House Book and Registration Book with an audit trail, tax calculated per your specific municipality's rates and exemptions, and integrations with your actual booking calendars.

Which is cheaper?

Guestbook costs 300 CZK per apartment per month (225 CZK per month billed annually), regardless of occupancy. Best Guest is priced per completed guest check-in — so seasonal operations don't pay for empty months. Which comes out cheaper depends on your occupancy; see our pricing page for current rates.

Does Best Guest have smart locks and card payment of the tax?

Smart locks, yes — Best Guest supports both TTLock and WeLock, issuing a door PIN automatically for every reservation. Card payment of the accommodation tax is still on our roadmap; if that's what you need today, Guestbook has the edge there. Tax calculation, reports for the authority, and the full set of registration obligations are covered by Best Guest already.

I mostly host foreign guests — what's the difference?

Guestbook offers its registration form in Czech and English. Best Guest guides the guest through the entire check-in in 43 languages and gives them a full web app with stay details and instructions — a guest from Germany, France, or Ukraine fills in their details in their own language, which means fewer errors in the data you report to the police.
