Dawn's place is great! We have direct view to the Golden Gate, the bay, and with binoculars you even get to see the Golden Gate. It's walking distance to the coit tower, pier 39 and other great spots. I spent a whole month there and it was very convenient to get everywhere; I got the monthly Muni pass for $100 which covered the muni buses (usually $2.50/ride) as well as the cable car rides (usually $7 each way). A car won't really get you to places any faster than public transportation in SF, so I highly recommend it.
Her place was very spacious, quiet (her street is well-hidden and not in the way of direct traffic) and comfortable. 5 stars!
