Why Flatio?

Final prices – everything's included

At Flatio, the rental prices you see are always final. That means no hidden fees, no surprise charges – just clear amounts that cover Wi-Fi, utilities, and fully equipped properties.

List your apartment for free

That's right – listing your apartment on Flatio is free of charge. We only ask for a commission once a tenant rents your flat.

Is Flatio a real alternative to Booking.com for landlords in Opatija?

You probably have experience with websites like Booking.com, VRBO, Flipkey, Expedia, Hotel.com, Tripadvisor, Spotahome, Uniplaces or HomeAway. They are worth trying because they are similar to Booking.com. But only if you still want to rent out your property to tourists for their vacation in Opatija. If you want to keep communicating every day with new tenants and spend a huge amount of time cleaning, changing sheets/towels and doing laundry, then keep renting with them.

But if you are looking for a true alternative to Booking.com you should question if short-term rentals are really the best for you. Because using another vacation rental site means you are still in the short-term rental business with all the pros and cons (like local regulations and taxes in Opatija or unhappy neighbors). If you want a real alternative, you should start renting to a mid-term rental market. This means renting out your property for 1 to 12 months to completely different travelers than tourists. You’ll mostly encounter business managers, IT specialists, expats, digital nomads or young professionals. Simply stated, they’re people like you who want to stay in Opatija for several months because they have a job opportunity or just love living in Opatija while working remotely.

Start with the true alternative to Booking.com right now and join thousands of landlords at opretnama.sbs, the best solution for mid-term rentals.

Flatio story

Flatio is the clever way to rent. We connect landlords in cities all over the world with tenants looking for a home from a month to a year, simplify paperwork, and secure payments.

We started Flatio after years of experience renting properties to students and young professionals. We understand how important it is for landlords to make their property attractive to the right tenants, and for tenants to select the best local neighborhood and amenities for their needs. We set out to use the latest technology and security to automate the rental process, from painless first contact between tenant and owner to a satisfied key handover when the tenant moves out. And even though we operate in many cities internationally, we get to know each location advertised on our site in great detail so that we can help landlords and tenants find the perfect match.

We know that renting a property requires a lot of trust — from both sides! — and so we have made our rules and rental agreements as fair as possible so that both tenants and landlords are in a strong, secure position. The rental contract is between the landlord and the tenant but, like a good neighbour, we’re here to help whenever necessary.
