We stayed at Kate's cottage for two nights with out 8 year old son, and all enjoyed our stay. The accomodation was well-equipped and comfortable. Kate provided good quality food and drink items which was much appreciated. There was parking space for our car, and a small kid's playpark is right across the road.
The location is great. Redwood City has a nearby downtown area which has grocery stores, restaurants and shops. It's convenient for San Francisco for both train and driving. We drove into the city and it took us only about 35 minutes. It's handy for the 101 freeway.
Kate was a great host, communicated really well before our arrival and gave us all the information we needed on arrival.
Would be a great option for a longer stay. Unfortunately we were just passing through before flying home (also convenient for SFO airport).
