What is CasaMio?

CasaMio is software for managing holiday homes: bookings, calendar, guests, cleaning, rates and finances in one system. It is developed by Altena and runs live on casamio.app, in fifteen languages, for landlords throughout Europe.

One holiday home rental is possible. Two becomes exciting. Three and you lose your weekend keeping track of which calendar is right again. Because the bookings come in via Airbnb, Booking.com and your own site at the same time, and those three do not talk to each other. Until someone double booked.

CasaMio puts one calendar over it. Sync all channels via iCal, the cleaning knows when to change, the guest gets his check-in instructions automatically, and at the end of the year a file rolls out that your accountant can use.

For whom?

For anyone managing a holiday rental.

From one apartment by the sea to a wallet with ten objects in three countries.

Owners of one or a few holiday homes who do not want to keep records in three separate calendars and a spreadsheet.

Whoever manages houses for others and needs to be able to account for what came in, what went out and who was there when.

03

Teams

Landlords who work with a cleaning crew, a handyman or a local contact and want to give everyone the same overview.

You don’t have to choose between CasaMio and the platforms where your bookings come from. Via iCal, availability is synchronised with among others Airbnb, Booking.com, VRBO, Holidu, Belvilla and HomeAway. If you book someone somewhere, the date is blocked everywhere.

CasaMio is built by Altena as own SaaS product: the same type of software we also use build on commissionMultilingual, multi-tenant, with user management and subscriptions underneath. Do you want to know how such a platform is created? our approach.

Frequently asked questions

Clear answers to frequently asked questions.

Who made CasaMio? CasaMio is developed and maintained by Altena, a Dutch software company owned by Marcel Altena.
Does it work with Airbnb and Booking.com? Yes, via iCal synchronization. Also VRBO, Holidu, Belvilla and HomeAway walk along. As soon as booking is made somewhere, that period is occupied in all calendars.
Can I try for free? You can try CasaMio for 14 days, without a credit card. Enough time to set up your first house and make a real change.
In which languages is CasaMio available? In fifteen languages: Dutch, English, German, French, Spanish, Italian, Portuguese, Polish, Croatian, Swedish, Danish, Norwegian, Czech, Greek and Turkish.
Can my cleaner access the system too? Yes. With the team function, you give employees your own access, so that the cleaning and maintenance tasks are visible without anyone being able to access the finances.
How do I send my figures to my accountant? It’s been set up so an accountant can get on with it right away without rearranging an afternoon.
In practice

How to evaluate CasaMio.

Follow one booking from availability to cleaning.

The problem: with multiple accommodations, calendars, guest details and cleaning arrangements become fragmented. CasaMio brings these parts together. The product images on this page show the occupancy, bookings and cleaning planning.

In a demonstration, check how a booking appears in the calendar, what information is in the guest’s possession, and how the cleaning schedule fits in. This is how you assess the product using your own rental process.
