Zhen is very responsive which really helped (e.g. I arrived 30 mins before check in time, and my door code didn't work yet. I messaged Zhen and she quickly updated it to let me in).
The house is in a nice area, you can walk to all restaurants and to the Caltrain. As she mentions on the description, you can hear the train, but that didn't bother my sleep at all.
Room is spacious and bright. Bathroom is big and has lots of different shampoos and stuff (so much better than the crappy little shampoos they give you at hotels).
Very nice place.
