Fast check-in/check-out is a digital key system that allows you to check in without visiting the reception.
On the day of arrival, you will receive a personal key code via SMS, which you need to enter on the door lock to your room. On the departure day, you will receive a new SMS with a link that you can use to check out. After approving any possible charges, you can check out online and be ready for departure.
If you need assistance or prefer to check in using the traditional method, you are always welcome to approach the reception.
