We booked the Arc Hotel as an overnight stop on our way to the South of France. On check-in the receptionist confirmed that our stay was pre-paid. She was very helpful and provided a map of the local area. The hotel is in a great location with direct access to the beach, our room was spacious and overlooked the garden. We spent an enjoyable afternoon in Arcachon and in the evening found a delightful restaurant close to the hotel which served very good food. On our return to the hotel we found that while there was a bar it was not staffed. When asked the receptionist brought drinks to our room. However, in the morning, on check-out, the morning receptionist demanded full payment, not only for local taxes and our drinks, but also for the room charge. Even when we showed her Hotels.com booking confirmation, which clearly confirmed our pre-payment, she was insistent that full payment must be paid. Unhappily we presented our credit card, which for some unknown reason was refused. We therefore paid in cash. We contacted Hotels.com immediately on arrival at our destination. At the time of writing this review our dispute over double payment with the Arc Hotel and Hotels.com has still not been resolved. This has not been a happy experience.
