Apartments for Every Lifestyle

Looking for a one bedroom apartment for rent on Mercer Island? Quickly find just the right floor plan at Island Square. Start by selecting the number of bedrooms you're looking for. You can also narrow your search by price, square footage, and number of bathrooms. If your desired floor plan isn't available, be sure to sign up for our apartment alerts and we'll contact you by email or text (whichever you prefer) to let you know when it is.

About Our Pricing

Pricing and options can vary based on lease terms, move-in date, and availability, and may change at any time. Specials or concessions may be offered depending on lease length and move-in date and usually apply only to the first full billing cycle. Restrictions apply, and specials do not apply to current residents, transfers, or anyone who lived with us in the last 90 days. Deposits may change based on credit, rental history, or other qualifying standards. Furnished homes and corporate leases may have additional premiums. For leases starting on or after the 25th of the month, your move-in balance will include prorated rent for the current month plus the next month’s rent (not applicable in Massachusetts). In New York, leases starting within 10 days of the upcoming month will include prorated rent for the move-in month plus full rent for the following month. In Massachusetts and Colorado, the total monthly price includes base rent plus any required monthly charges. Floor plans are artist’s renderings; actual layouts, sizes, and features may vary. Not all features and amenities are available in every home. Occupancy guidelines may apply. Equal housing opportunity provider.
