We hven’t stayed in the hotel. We could not arrive on the day of booking for health reasons. We requested moving check in by 2 days. It was refused by the hotel. So we stayed elsewhere in the end. There is no way to type any message to state reason when requesting rebooking. And so we havent got any reason for refusing rebooking by hotel. This communication should be really improved by rbnb. We then rather used booking.com for all the rest of our booking where free cancelation is much more available and communication with hotels is much better.
