What Our Users Say

We succeed when our properties do.

“Della is the solution to all of your building problems and then some. I am a property manager and have used many different interfaces to manage numerous buildings, and I have never come across something so intelligent. It is extremely easy to use, and the app is so clean and user-friendly.”

KM

Property Manager

“If you're like me, you probably never write reviews but still appreciate reading them. Well, Della impressed me so much that I had to make an exception. I'm not kidding. I was actually considering moving, but then Asset Living, our new property manager, brought in Della, and it completely transformed my living experience. My building and my unit feel revitalized in a way I didn’t expect. I've always been frustrated by how incredible buildings often lack basic tech features, like having a luxury car with an analog radio. Finally, someone did something that genuinely makes a difference. Everything just works, and it’s so easy to use. A big thanks to whoever decided to bring Della into our building.”

Justin

Resident

“As a resident whose property recently onboarded Della, I've been thoroughly impressed with the smart features it offers. Being able to control my apartment's temperature and receive instant building updates has made my life incredibly convenient.”

Mike

Resident

“Della is a game-changer! The Della Connect dashboard's powerful capabilities have elevated how I manage my properties to a whole new level. Five stars all the way!”

Kaley

Property Manager, Asset Living

“Della is amazing. We had a hard time with all things in our building before Della. Things like getting in touch with the property management was always a struggle. Having multiple apps for everything and struggling to navigate it all was so frustrating. But Della somehow managed to absolutely impress me. It's so easy and smart. Does Della have other buildings? I would seriously only consider living in a building with it. Love love love Della.”

Alison

Resident

“This app is awesome! It's super easy to use and has everything I need to control my house all in one place. I've never had such a convenient way to manage everything in one place. Totally recommend it to anyone!”
