Due to an error in the booking system of Guest Reservations, our hotel reservation was confirmed twice within a span of two minutes. It is technically impossible to complete two separate bookings in such a short timeframe. Despite this clear glitch, Guest Reservations refused to refund the duplicated charge, stating that by completing the booking, we agreed to their terms — even though the second confirmation was triggered by the platform itself, not by us.Moreover, this platform is highly misleading. It gives the impression that you're booking directly through the hotel’s official website (in our case, UNA Hotels), only to find out later that you’ve unknowingly used a third-party platform.To make matters worse, at the end of the booking process, an additional fee of nearly €500 was charged — and to be clear, this is not a city tax. No transparent explanation was given for this charge.We are currently exploring legal action and wish to use this review as a warning to both potential travelers and hotels. From our experience, this platform engages in practices that are deceptive and highly questionable, if not outright fraudulent.Avoid Guest Reservations at all costs.24.04.2025 - Addendum following the response from Guest Services to my review:We would like to point out that we already informed your company more than a week ago of the issue via the email address you mentioned below. Unfortunately, we have not received any response to date.
