Pretty home nestled into the west facing Castro Valley hills. From the living room, with old oak floors and a brick fireplace, you can watch time slip away as the sky over the Bay changes from day to night. This is a unique property: from the shape of the lot to its custom build in 1954, and still solid. Like other hillside properties in the area, this one has a ground level bonus room but this has, adjacent, an unusually large garage. The house feels and really is bigger than the listed 1,254 sf. Interestingly, the original builder’s family will pass the keys to the next owner who will undoubtedly add to the home’s charm and longevity.
