citizenM, developed by citizenM Operations Holding B.V., is a free travel and navigation app that simplifies your stay at any citizenM hotel. The app allows you to sail through your entire stay without visiting the front desk, except to pick up your key card.

Before your stay, the app lets you begin check-in and keep your stay history in one place, even if booked via other channels. The app also provides you with city tips from locals and a free welcome drink with every booking made through the app.

Once you arrive at the hotel, you can go straight to your room with a completed app check-in. The app also allows you to control your room's lights, blinds, and temperature like a Bond supervillain. You can even stream your own shows and series to the room TV and browse food and drink menus.

After your stay, you can check out without stopping at the front desk and download your stay invoice right away. The app also lets you see all your previous citizenM stays and earn travel badges.

Overall, citizenM is a must-have app for anyone staying at a citizenM hotel. Download it now to enjoy a seamless and personalized hotel experience.
