This classic Balboa Island cottage offers far more than meets the eye, with five bedrooms in the main home and an additional bedroom in the separate downstairs apartment-providing plenty of space for friends and family. The main house features a spacious front patio, an expansive living room with vaulted ceilings and a brick fireplace. There's a charming window seat in the dining area and a well-designed kitchen. Just three doors from North Bayfront and steps from Marine Avenue's shops and restaurants, this convenient location means the best of the Island is steps away, and getting on and off the Island is a snap. A wider-than-average two-car garage adds valuable parking, while the separate apartment offers flexibility as a guest suite, income property, or potential expansion of the main home into a downstairs primary suite or additional living space. Lovingly owned by the same family since 1969, this classic Island cottage is now ready for a new chapter.
