Property Description

Welcome to Unit 115 at Tidelands — a bright, ground-floor residence in one of Mariners Island’s most sought-after communities. This 2-bedroom, 2-bath home offers about 1,353 square feet of open living with hardwood floors, large windows, and an easy indoor-outdoor flow to a private balcony. The living, dining, and kitchen share one generous space. The kitchen is built for everyday cooking and entertaining, with a quartz island, gas cooktop, stainless appliances, and room for stools at the breakfast bar. A built-in bookshelf alcove off the main living area works as a den, office, or reading nook. The primary suite is a true retreat: generous bedroom, walk-in closet, and an ensuite with dual vanity and a glass walk-in shower. The second bedroom and full bath with tub/shower combo give guests or work-from-home space their own wing. In-unit laundry adds convenience. Tidelands living includes a gym, clubhouse with billiards and table tennis, community kitchen and lounges, and outdoor BBQ areas. Assigned garage parking and guest parking keep daily life simple. Walk or bike the Marina Lagoon trails, reach Seal Point Park and Foster City dining in minutes, and connect quickly to Highway 101, SFO, and the Peninsula job centers. A rare first-floor Tidelands home — open, light, and ready for its next chapter. Information provided is deemed reliable but is not guaranteed.
