Supatra and Glenn are so lovely. They help wherever they can and are open for some nice chats. They lent us their bikes and we could swim in the pool which will be shared by the neighbours but nobody was there so we had a very relaxing afternoon alone at the pool :-)
The bathroom was clean.
The place is a little far from SFO and not that easy to reach but it is possible. Foster city is a nice and quiet area with a beautiful central lake.
