The West Loop and Fulton Market are the hottest place to rent a new high-rise in Chicago, and three buildings keep coming up. We pulled their live numbers, read their amenity lists in full, and cross-referenced what residents actually say. Here is how Onni, Fulbrix, and Arthur on Aberdeen compare, and who each one fits.

Onni Fulton Market: the rooftop-pool tower

Onni is the tallest of the three, a 32-story tower with 373 residences and floor-to-ceiling-window units with quartz counters and smart-home features.

Its 32,000 square feet of amenities are built around the rooftop: an outdoor pool and hot tub with skyline views, plus two infrared saunas, a steam room, a fitness center with a private Tonal studio, lounges, co-working rooms, fire pits, parcel lockers, cold storage, and EV chargers. In-unit washers and dryers come standard.

The resident reviews capture the vibe well. One renter said they feel like they are on vacation every day they come home, praising the views and the welcoming staff. Others single out how the amenities stand out from other buildings and how the team goes above and beyond. Studios start around $2,100 and one bedrooms around $3,276, near the Grand Red Line stop with a Jewel-Osco close by.

Fulbrix: the amenity heavyweight

Fulbrix makes a simple claim: the largest amenity package in the West Loop, at 30,000 square feet. And it backs it up.

That includes a golf simulator, a large fitness and yoga studio with SoulCycle bikes, an outdoor Sky Terrace with a fire pit, a private dog run and pet spa, a resort-worthy pool deck, and co-working areas built for remote work. The design leans high-end too, with Ligne Roset furnishings and custom art throughout, and a 24/7 doorperson.

Residents respond to all of it. Reviews highlight the great location, the friendly and efficient staff, the standout amenities (the golf simulator and the outdoor spaces get named a lot), the 24/7 gym, the nicely sized units with quality finishes, and quick maintenance. It carries a 4.4 across more than 50 reviews, with one bedrooms starting around $2,919, near the Ashland Green Line stop with a Mariano's close by.

Arthur on Aberdeen: the highest-rated, and the best entry price

Arthur on Aberdeen is the resident favorite of the three on the numbers, at 4.8 stars, and it pairs that with the most accessible pricing.

The amenities are genuinely strong: a rooftop terrace with skyline views, a rooftop pool and hot tub, an outdoor pool with a sunbathing terrace and private poolside cabanas, a fitness center with a yoga and stretching studio, a sauna and steam room, co-working space, bike storage, and pet amenities. Units come with in-unit washers and dryers.

The reviews are glowing and consistent: clean building, kind staff, beautiful units, great views and amenities, friendly residents, and fast maintenance. Studios start around $2,299 and one bedrooms around $2,958, the easiest entry of the three, near the Morgan Green and Pink Line stop with a Whole Foods close by.
