Sandy provided me with an incredible stay at her house in Fremont. Her neighborhood is unbelievably charming and safe. As advertised, the location is pretty much 0-3 miles from almost all points of interest in Seattle. She keeps the house very clean and comfortable for her guests and has a very friendly dog as well. Sandy is very conversational and knowledgeable about points of interest in town. She has her own routine, so it is likely that you will not always be around the house when she is present, but ask her for any pointers that only a local would know.
The Space Needle, the Queen Anne District, and Pike Place market are about 1.5-2 miles of walking away from her place. The UW campus has a nice running trail leading into Fremont, so there are many paths and locations to explore starting from Sandy's house.
Sandy has a very nice house and price for someone looking to venture into Seattle for a few days and I would stay for a second time.
