We stayed at Sandra's place almost for two months and really enjoyed our staying. First of all location is absolutely amazing - very close to Castro subway station, and walking distance to Haight Ashbury, Mission Dolores Park and Castro itself. Whole Foods and Safeway are 10 minutes by foot.
The backyard is absolutely lovely place to have a breakfast and enjoy the sun till noon and even later.
If you have a car there are some streets within walking distance without residence 2-hour limitations: Haight street and all the way along Buena Vista Park. If you park you car there you will get home in 10 minutes by foot (but be aware that coming back to get the car will be uphill :)
The apartment is very cozy, has a lot of nice tiny details such as paintings on the walls, a lot of beautiful pottery. Landry is in the garage with was super convenient and kitchen is fully equipped. Wifi was very fast and worked always.
There were only few little comments: the living room is too dark to spend there all day, but if the day is sunny you can go to the backyard which is way better. Also the ceiling height is quite low - it was fine for us, but if you are a tall person you may feel uncomfortable. And the last one there are a lot of carpets on the floor, so if you are allergic this may be an issue.
Overall experience is great. Sandra and Michael were very helpful, accommodative and responded very quickly. We can definitely recommend this place!
