I wanted to add some extra nights to my booking one moenth in advance. That was only possible via a really slow chat, I had to wait a lot to get any reaction. As soon as I didnt answer quickly the chat would get disconnected and I had to start from the beginning again. They cahrge 95€ to make any changes of the booking, as soon as the money has been payed. Then they charged the normal price of any extra days, instead of applying the week deal that they apply on their website for any customer. Very unfriendly. The costs to cancel the booking one month in advance are the same amount of the total price, so it means you actually cannot cancel it. Very untransparent company.
