How much does Travala cost?

I'm curious, could you please clarify the cost of Travala for me? I've heard it's a popular platform for booking travel accommodations using cryptocurrency, but I'm unsure of the exact fees or pricing structure. Is there a standard fee per booking, or does it vary depending on the type of accommodation or length of stay? Additionally, are there any hidden costs or surcharges that I should be aware of before making a reservation? Thank you in advance for your assistance.
