Warning: STAY AWAY

Warning: STAY AWAY
Warning: Avoid Onni South Lake Union Apartments
If you're considering living at Onni South Lake Union, I strongly advise you to think twice. My experience with this building was nothing short of a nightmare, and it cost me nearly $15,000 to break the lease after signing what seemed like a promising agreement. Here’s why:
False Promises, Rudeness, and Unprofessional Behavior
When we first toured the property, the staff and leasing team were friendly and professional, eager to...
help us with anything we needed. However, after our first complaint about the conditions and our request to break the lease, their attitude changed drastically. They became rude, dismissive, and careless. What started as a seemingly professional relationship turned into complete disregard for our concerns. The moment we expressed dissatisfaction, the kindness vanished. They showed no empathy and refused to help, making the process of breaking the lease even more difficult.
Health Issues and Abandonment
Unfortunately, after breaking the lease, we had to leave Seattle for health reasons and never spent a single night in the apartment. We asked Onni to hold on to a couple of our furniture items while we sorted things out, but they discarded them without warning, claiming they only held onto them for 30 days. No one reached out to inform us about this policy. It felt like they wanted to make things as difficult as possible for us.
Unsafe and Disturbing Environment
What they don't tell you is that Onni South Lake Union isn't just a residential complex—it doubles as a hotel. This brings in a constant flow of transient guests who are not invested in the community, and it drastically changes the building’s atmosphere. The lobby and common areas are often crowded with groups of people who do not live there, which includes young women who appear to be using the space for gatherings that made us feel unsafe and uncomfortable. It felt more like a party venue than a place to call home. The combination of the hotel and constant strangers made the building feel less secure and far from the peaceful, upscale environment we expected.
Facilities and Maintenance Neglect
On top of that, the building’s facilities were a disaster. From the broken sauna to filthy pool areas and drainage problems, nothing was properly maintained. The building was not up to the standards that we were promised. The common areas reeked of marijuana, and there were safety hazards everywhere.

Moving Made Easy

I have been a resident at Onni for over a year now, and have loved my time here so much! I am moving into a new unit in the building and appreciated the streamlined abilities of the staff, especially Sarah Ahn, in advocating to have the perfect apartment unit held for my partner and I until we could move in. Sarah has been there to support us, offer resources, and answer questions along the way. I highly recommend Onni not only for the amazing resident services team, but also for the incredible... amenities and overall experience Onni provides while living in SLU!

Guest services make Onni truly special

Onni is a great new building, but what makes it truly special is its guest services. Khadra, T, and Marlee make Onni a wonderful home to live in. Their kindness, reliability, and care elevate the experience in the building and bring joy to residents. This team makes all the difference in our experience! Whenever any issues or concerns come up, I can always count on them to understand and help. For example, Khadra was working on the night that we encountered a minor flood in our apartment, and... she managed to get us help repairing it even though it was late and we’d arrived home in the middle of the night. Her help fixing this allowed us to prevent further damage and more serious problems, and allowed us to get a good night’s sleep knowing this was resolved by someone who genuinely demonstrated care and concern. It brings us so much peace of mind knowing that we have this level of support!

Lack of basic hygiene

As a resident, I am extremely disappointed with the current state of the hallway in our building. The overwhelming smell of garbage is making it difficult to even walk through the hallway without feeling nauseous.

It is disappointing to see such a lack of concern for the basic hygiene and well-being of the residents. I am extremely dissatisfied with the living conditions in our building and cannot recommend it to anyone until this issue is addressed in a timely and effective manner.

I urge the...
building management to take immediate action to remove the garbage and eliminate the odor, and also to put in place a more proactive system for garbage collection and disposal to prevent a similar situation from happening in the future.

OSLU

We recently moved in to OSLU and love it! Joey was our leasing agent and was super helpful, knowledgeable and professional. He made the moving process a breeze! He gave us multiple tours of different units and floor plans until we found the one that was perfect for what we were looking for. Thanks, Joey! :)
