About Project

Our team had become an official tech partner of Vondereurope – an international сompany working in the travel and hospitality sphere. Their business is based on providing modern houses for digital nomads, students, and young professionals in smart hotels, which have everything necessary for career and personal development.

During our collaboration, we have been in charge of product management, developed the booking website, control panels, mobile apps, and have dealt with many 3rd party integrations.


About client

Vonder is a part of LRC Group, a privately held investment and management firm which have sourced and acquired real estate assets with a total value of over €6bn across Europe.



Our clients contacted us to develop a robust web platform with thoughtful UI design and including third-party services. The website needed to have an opportunity to book apartments in different countries, make payments on the site and have 24/7 online support. Furthermore, the website had to integrate maps with city guides where tenants would see the nearest supermarkets, pharmacies, places for entertainment, and police. Also, they wanted to create a smart lock system that would allow renters to use their smartphones instead of the keys.

Third-party API integrations

Third-party API integrations were an essential element in the work of our team, and we have done a bunch of 3d parties integrations to make a platform and meet all specifications. Thus, we implement the following third-party services:

  • Arthur online – cloud-based property management platform with a functionally rich suite of apps designed with your business in mind.
  • Saltos – Cloud-based access control for smart locks solution.
  • Sendbird – a service that gave chat and messaging experiences with delivery receipts, offline messaging, presence, translation, moderation tools, and analytics.
  • Frontapp – the customer communication platform that combines emails, apps, and teammates into a single view.


Our next essential task was to implement a smart lock system. We provided back-end development, where we integrated a smart lock with an in-house hotel system using Saltos. As a rule, smart locks use Bluetooth to interact with smartphones, which operate at short distances, making it both convenient to use at home. But renters would have a choice. They would be able to use both Wi-Fi and Bluetooth networks to establish a connection with the smart locks. Having access to the smart lock system, the renters can automatically open the door and have the ability to share virtual keys to other smartphones, and can remotely control the lock from a smartphone via Wi-Fi.


The booking system on the site was the main feature and customer’s requirement. The integrated booking system that was directly connected to the customer’s internal CMS system significantly simplified the booking and communication process. Besides, such a step helped our clients to avoid double-booking and streamline internal processes. Our work started with creating the booking bar and registration form. We included the possibility for users to select the city, dates, and apartment type. Users could see extended details such as a list of available apartments and their locations, see rooms design and photos with their choice. Also,  we connected a third-party service that allows making a data verification in real-time.

Upon completing the project, the customer received a robust and user-friendly website, which quickly attracted the attention of many young people. Using third-party services has helped boost up the development process and bring the best result for our client.

In the first few weeks, the site received more than 5000 unique customers who booked rooms in smart hotels and were satisfied. At the moment, our clients, with the website, have increased their profit and brand recognition several times.
