We booked a Suite (60 m2 with panoramic sea view, sofa) & were charged £463 in advance. When we arrived, told our room unavailable due to problem with bathroom. Asked what was wrong with bathroom, manager unable to say but offered another room "as good" as what we'd paid for.
When we saw it, hugely disappointed as only had partial side-on sea view (mostly looking over carpark at back) and only 22m2! One chair to sit on instead of sofa, nowhere near as nice as Suite booked. Felt we had no choice as we had already paid, so accepted the room on agreement we would be refunded difference in room rate between room & what we'd paid for.
Asked repeatedly about refund during stay. On checkout told it had to be sorted out through Hotels.com later. As we were leaving saw the manager pulling same stunt on another couple being shown different room to one expected! Wonder how often hotel books out expensive rooms and then bumps guests down to inferior ones.
After we left, informed we'd been refunded just £57, nowhere near difference in price between the two rooms according to hotel's website (room given was three price levels below what we'd paid for, refund should be nearer £150 inc. taxes).
Hotels.com hiding behind excuse that hotel refusing to pay refund. Surely this is fraud, to charge £463 upfront for 62m2 Suite but provide a 22m2 inferior one, then refuse to refund difference. So our advice to anyone considering a stay at the Hotel Grand in Perros-Guirec is JUST DON'T
