monthly savings
Apartments with an innovative approach to digitalisation and automation have shown how to simplify operations while improving service quality.
Kampus Apartments are modern apartments in Hradec Králové, which fall under the Apartments 4U brand. They offer comfortable and stylish accommodation for students, tourists and business travelers. Thanks to their excellent location near the university campus, full amenities and self-service check-in, they provide guests with maximum comfort and independence.
“The integration of Previo and Keyguru gave us complete control over everything happening in our apartments.
We know when guests arrive and leave, when the cleaner comes, and how long cleaning takes. For me, it’s a huge saving of time, stress, and money.”
1. Challenges
Before automation, Kampus Apartments struggled with time-consuming management and lack of operational visibility.
The manual system created security risks and unnecessary administration:
- Monthly manual updates of PIN codes across automated messages in 13 languages
- Difficult maintenance and risk of damage or break-ins with mechanical lockboxes
- No clear overview of guest arrivals and departures
- Lack of visibility into cleaning processes and staff efficiency
- Ongoing need for personal coordination despite partial automation in Previo
2. Solution
Implementing a connected system – the Alfred virtual receptionist (Previo) and Keyguru boxes with the Gatekeeper access system — transformed the entire operation.
Automation eliminated manual handling of lockboxes and simplified overall management:
- Guests receive an automatic email with an online check-in link after booking
- After completing details and payment, the system generates a PIN code
- The same PIN is used for building entry (Gatekeeper) and key collection (Keyguru box)
- Alfred automatically updates reservation status after check-in
- The owner has a real-time overview of guest and staff movement
- The system reduces human error and saves both time and operational costs
3. Results
The new solution significantly simplified operations, saved time, and improved satisfaction for both guests and staff:
- ~30 hours saved per month = approx. €800 in cost savings
- Increased bookings thanks to 24/7 booking and check-in capability
- Full control over guest arrivals, departures, and cleaning schedules
- 5–10% reduction in cancellations due to flexibility and convenience
- Improved security by eliminating mechanical lockbox risks
- Higher guest satisfaction and better reviews thanks to simplicity, privacy, and flexible arrival times
“Thanks to automation, cancellations dropped by 5–10%. More people now prefer self-service accommodation where they don’t rely on someone being there with the keys.”
Michal Koza, the owner
By combining the Alfred virtual receptionist (Previo) with Keyguru boxes and the Gatekeeper access system, Kampus Apartments became a fully automated operation with complete control over every movement.
Modern technology ensures smooth operations, security, and comfort – for both guests and staff.
This case study clearly shows how automation with Keyguru and Previo enables apartment businesses to run efficiently, stress-free, and with full control.
