I've stayed at the Lighthouse Apartment Building before, and that's why I returned.
The location, size, and amenities were all perfectly adequate for me.
However, this time, something was different during check-in. It turned out the apartment I'd booked wasn't under Imagine Lighthouse, but Lumina Lighthouse, even though the apartment I booked and the confirmation I received stated Imagine Lighthouse. I don't know what the problem was, but because of this, I couldn't get service from Imagine Lighthouse management, even though I'd stated I'd arrive at the location at 7 a.m. Melbourne time. I had to wait almost two hours before finally, after several communications via the app, Imagine Lighthouse Management, and a phone call to Lumina Lighthouse Management, a representative from Lumina Lighthouse met me, quickly and smoothly checked me in, and handed me the keys to the apartment, allowing me to rest after my all-night flight. According to information I've gathered, some apartments in the Lighthouse Apartment Building are managed by Imagine Lighthouse Management and others by Lumina Lighthouse Management (I'm not aware of any other management companies besides the two I mentioned). I don't know which one is managed by who, but I do know that I booked through an app called Imagine Lighthouse.
Aside from the aforementioned issues, my stay at the Lighthouse Apartment was generally pleasant.
