Sharon's studio (a studio space behind their main 3 bedroom house) was as described. Having A/C on a day that hit 90 degrees was a great amenity, and certainly not something that is a guarantee in Bay Area homes.
The studio is perfect for one (or maybe two) people. The bed is firm but comfortable, Sharon had provided a simple amenity care pack (some bottled water, chips, Kuerig Coffee pods) that was really appreciated. The studio has a combined washer/dryer which is nice.
Only item to note, you will be sharing a driveway with 3 different units - the main home (3bd), the studio (this unit) and a second studio which is a converted garage in the back yard. So you will be chatting with some of the folks around you to move your car (in my case, the folks who were renting the front unit).
If you are visiting the bay area Sharon's unit is a great choice for value, location and attention to detail.
