William and Emma are wonderful super hosts who treat you like family. The unit is very comfortable and clean with some unique special extras: electric fireplace in the living room is extremely cozy on cool evenings or crisp mornings; soup ready and waiting for our dinner after a long flight included crispy bread, wine, and a candy selection for dessert; a bag of breakfast breads; a kitchen stocked with coffee pot (ready to brew upon arrival), teapot, cooking pans, utensils, and cutting boards; dining room could seat a family for the holidays; address is very near the West Portal neighborhood, which is my favorite in SF, and was close to our family as well, and I saved the best for last: a deck in the back has a sweeping view of the south city and bay, lovely at night, at sunrise, providing pleasant outdoor seating at any time. William was always available for our questions yet not intrusive at all . We felt like guests, not renters, I would highly recommend this Sunnyside location.
