1. Mandatory Online Check-in (Prerequisite for Stay) After booking, all guests receive a separate guest app. Complete online check-in via this app is mandatory. All required information must be provided; in certain cases, identity verification via ID card is also required. Accommodation is not possible without a fully completed check-in. Access to the apartment is granted only after successful verification. 2. Check-in & Check-out You can find the exact times in your booking confirmation and in your guest portal. Earlier check-in or later check-out is possible – subject to availability – for an additional fee. If the agreed check-out time is exceeded or our cleaning is delayed as a result, guests are liable for all resulting costs. 3. Booking from Your Own Place of Residence Reservations from your own place of residence are not permitted. In exceptional cases, please contact us in advance. 4.
