Though I haven't spend a lot of time in a flat as my trip was business related - staying in the place brought very good experience! Location of Carrie's place is wonderful - many great food spots just by 5-10 minutes walk, area is clean and looks safe (comparing to other SF districts where I've stayed before). Also just ~20 mins walk to reach Finance District. Also I was surprised how quiet neighborhood is during the night time.
Talking about the flat itself - not much to add here. Place is clean, cosy, all required amenities, with comfortable kitchen. I didn't have a chance to cook something in a kitchen so can not comment if there are everything what you need, but from the first look - it should. Also probably visiting the place with young child (~2y) would make some trouble as there are A LOT of easy to reach things. But in general, I loved this place and definitely would stay again here or in similar area!
P.S. I almost forgot to mention Carrie's communication which is golden here! She responds immediately :-)
