Answer
A traditional lease in Montevideo, including utilities and building fees, may be only slightly cheaper than renting through Airbnb. The difference is not always large because regular building charges and utilities are added to the long-term rent.
Airbnb may offer a small discount, especially for a longer stay, but compare the total cost after factoring in fees, cleaning and cancellation terms. The platform offers the convenience of reviews, payments and dispute resolution, while a direct lease requires more preparation on your own.
For the first month after a move, Airbnb or a similar platform is often convenient because of its flexibility. For a longer stay, a lease may be more economical if the costs, security deposit, term and neighborhood are clear. Compare not merely the type of lease by name, but the total cost for the same period.
