Vacation Rental at Risk: How Landlord Delphine Protects Herself from High Costs with Smart Technology
Imagine renting out a vacation apartment that you've carefully furnished. But what happens when your guests' misconduct — such as ignoring the no-smoking policy — suddenly causes major damage? In our interview with an affected landlord, we talk about experiences like this and the solutions available.

Delphine, who rents out a vacation apartment in Halle, knows the problem all too well. After an expensive damage incident, she found a solution with the air-Q air quality meter that protects both her nerves and her apartment. In this interview she shares her experiences and explains how the smart technology helps her identify problems early and act preventively, so she never has to go through an incident like that again.
You had an unpleasant damage incident in your vacation apartment that you had to pay for yourself. What happened?
"In 2022, an incident occurred in my vacation apartment: guests ignored the no-smoking policy and smoked in the apartment for a whole week. Despite intensive airing out and ozone cleaning, the smell of smoke persisted stubbornly and settled into the furniture. Since such damage isn't covered by my insurance and I had no evidence against the guests, I had to replace several pieces of furniture and suffered a financial loss of several thousand euros. It was a very unpleasant and costly experience."

How did you come across the air-Q and why did you decide on it?
"I chose the air-Q because conventional alarm systems are very expensive and don't solve the smoking problem, and surveillance cameras are of course not an option. The device offers me great added value, plus extra comfort and safety for my guests, by flagging pollutant exposure early. I also receive push notifications as soon as someone smokes in my apartment, so I can react quickly to prevent damage."
You've now been using the air-Q for some time. Are you still convinced by it?
"Yes, absolutely — it gives me peace of mind by informing me early about problems and also showing when the apartment is entered. This lets me check the key handover remotely, for example. The app delivers insightful data and sends push notifications for high pollutant levels or entry, so I can react immediately. Compared to the previous damages, the investment in the air-Q was minimal, but it offers considerable added value for me and my guests and helps prevent incidents like that from happening again."
