About this unit

Experience an exemplary Streeterville lifestyle in this sun-filled one-bedroom, one-bathroom residence, perched high above one of downtown Chicago's most walkable neighborhoods. Unit 510 is the largest one-bedroom floor plan in the building. Hardwood floors run throughout, and picture windows flood the space with natural light. A large entry foyer welcomes you in before the space opens into the main living area. The living and dining space flows easily together, well-proportioned for everyday living. The kitchen has been newly refreshed with new plumbing and fixtures and updated counters, offering a clean, modern backdrop for everything from a quick morning coffee to a full dinner spread. The generously sized bedroom offers a peaceful retreat, calm and well-proportioned with a spacious walk-in closet. The bathroom features newly refreshed counters and all-new plumbing and fixtures. Closets are plentiful, giving this home a level of everyday functionality that's hard to find in a high-rise one-bedroom. An in-unit washer/dryer hookup is ready to go, a rare and welcome convenience only offered on this tier. Residents enjoy access to a full slate of building amenities, including an indoor pool, sauna, fitness center, sun deck, laundry room, and twenty-four-hour door staff. Just steps from Michigan Avenue's Magnificent Mile shopping and dining, Ohio Street Beach and the lakefront, and Northwestern Memorial Hospital. The Chicago Avenue bus and the Red Line train are both close at hand for an easy commute in any direction. Garage parking is included with the condo. This is the Streeterville home you have been waiting for.

Where it is

FAQ

Where do these listings come from?

Straight from the Midwest Real Estate Data (MRED) MLS, refreshed regularly — the same listings your buyer's agent sees, no curated subset.

Can I work with Dibze to buy?

Yes. A licensed Chicago buyer's agent lines up tours, writes offers, and handles the close. The seller pays the commission, so it's free to you — and we rebate part of it back at closing.

Can I rent in this building?

If owners are leasing units, the For Rent tab shows them. These are individual condo owners listing through the MLS, so lease terms and pet rules vary by unit.

How is this different from Redfin or Zillow?

Same MLS feed, different model — we don't sell your contact info or turn every click into a lead. One Dibze condo expert handles your whole search and represents you, not the seller.
