We stayed at Michelle's place in San Carlos for one week in August. It is a lovely home - and it was designed for a time San Francisco/the bay area were not extremely hot due to climate change. The home has windows and natural light everywhere - it faces east towards the balcony and is placed perfectly on the cardinal directions - meaning sunlight all days of time. It also had ceiling windows, which was a lovely experience especially in the shower, and was designed with ventilation in mind. The apartment was nicely renovated as well, and the kitchen was a nice large space with nice cooking space, and the space itself was big enough for four adults. The issue we faced space wise was the fact that the second bathroom was extremely small - probably installed in a remodelling, and so much so that no one really was able to use it comfortably, and we all ended up using one bathroom.
The only other notes I have is that if you do travel in the summer, the not having A/C can become an issue. It was hot when we went and because of how much light the property receives it gets even hotter inside. Unfortunately with the rising temperatures, it was uncomfortable during the day. Luckily during the night it was quite cool, and we slept with the window open (bewarned of allergies!). If you do choose to do laundry, the dryer does not dry in one load - it needs two runs.
Other than that the location was quite convenient to many areas in the bay area, and was driving distance (It is quite hilly in the area, so we did not walk much in the neighbourhood) to groceries and such amenities. It's also very close to half moon bay - which I definitely recommend checking out.
