We lived in this guest house for 4 weeks. The description and photos fairly depict the unit - it is small 1 bedroom detached house with everything one needs, dishwasher, washer and dryer, hairdryer, set of linens, everything. You definitely need a car to get to the place, I didn't see any social transport nearby. The house has a dedicated not covered parking space, even enough for 2 cars. Emerald Hills located conveniently in Bay Area, so you can reach pretty much everything in peninsula withing 20-40 minutes drive, SF, Half-Moon Bay, San Jose - all of this withing half an hour.
The area and neighborhood is very silent, safe and quiet. We sleep very sensitive, but we didn't have any problems sleeping by 10-11am.

Hosts live in the main house, they were supportive and helpful during our stay - even helped with some medicines when my wife got slightly seek. If you have any concerns, questions or problem - be sure, you will be helped and supported.

There were issues with internet though, sometimes it either worked extremely slow or didn't work at all.

We had very positive experience overall and can totally recommend this place.
