About this property
Perched high above the waters of Lake Union, this Penthouse Condo feels like a private observatory! The view is the centerpiece. Immediately upon entering the lake view greets you; dotted with sailboats & the motion of seaplanes gliding across the water. Next is the iconic Space Needle, framed as if part of the interior design & the downtown skyline standing tall. Enjoy these panoramic views from 2 decks!! Offering spaces for parties, dining, gathering, or just creating a backdrop for your quiet morning coffee. Inside, the updated kitchen is a showpiece! Quartz countertops, high-end appliances, & a massive island that invites gathering. The living area flows effortlessly into the dining space, all oriented toward the breathtaking views. High ceilings and a cozy fireplace add to the special vibe. The primary suite feels like a retreat with a deck overlooking the glassy lake. Generous closets & a spacious newly renovated bathroom complete the luxurious feeling! The 2nd bedroom, with its own newly updated bathroom nearby, positioned in the front of the home, makes the layout perfect for hosting guests or privately working from a substantial home office with a crazy view!! Not to be missed, there's an exceptionally LARGE storage unit included in the sale. It’s a unique addition that you won’t find anywhere else in the city! This wonderfully located penthouse is a lovely gem offering a front-row seat to Seattle’s most iconic views; a must see for your buyers!
