Check-in is available from 4:00 PM and must be completed by 9:00 PM at the latest. The process is entirely online and takes only about 2 minutes. You will then receive your PIN code via email, which you can use to open the entrance and your room door. Once at your room, enter the start code once to let the system know you have arrived.
21rooms is fully automated by design. You can come and go whenever you like, without being restricted by opening hours. If you have any questions, we are always available via email or our contact form.
Your PIN code works around the clock, even in the middle of the night. Simply check in online in advance, and the code will take care of the rest.
You can also complete your online check-in directly via our homepage - all you need is your reservation number and your last name.
complete online check-in• First name used instead of last name:
Most often, the first and last names were swapped during booking - meaning the first name was entered in the last name field. Since our system searches by last name during check-in, this leads to an error.
• Booking via third-party platforms or travel agencies:
When booking through portals like Booking.com, Expedia, or travel agencies, they sometimes assign their own booking reference, which may not necessarily match the reservation number in our system.
Still having trouble? Please get in touch with us - we will check our booking system and manually send you the check-in email to ensure your stay gets off to a smooth start.
After completing your online check-in, you will find your PIN code in the digital guest guide under "Door Opening"—you will also receive it via email. Please note that the code is only generated after check-in.
Check-out is by 11:00 a.m. Your PIN code will be deactivated automatically after this time.
At 21rooms, everything is digital—we use the Straiv system for your stay. You can easily manage your billing address yourself:
Entering & changing details at check-out: Forgot your company details or need to make a change? No problem—during the digital check-out process on your smartphone, you can quickly update your billing address and company name before finalizing the process.
Important note: Please make any changes directly in the digital guest guide before completing your check-out. While adjustments are possible afterward, the system will automatically issue a cancellation invoice and generate a new one with an updated number. To avoid this extra step, it is worth taking a quick look at your billing address before checking out. If you have any questions, you can reach us at any time at info@21rooms.de.
Our apartments are generously proportioned and designed to feel like a true home, even during longer stays. You can find exact square footage and floor plans for each room category on our overview page.
