For me this Airbnb was perfect because my sister and my brother-in-law live live in San Mateo CA and I chose this place yo ve near each other. Also, the neighbourhood looks very nice and safe. I really enjoyed my stay.
Also, this Airbnb is located in front of San Mateo Hospital Center, near Hillsdale Shopping Center, near a lot of local businesses around and not as far from the train station in case you are more interested to visit another cities in Bay Area (San Francisco, Redwood City, Palo Alto, Mountain View, San Jose).
There is a cat in the house... for me it was good because I am a catlover.
The bed and the pillows were very comfortable.
The desk was very good to put my laptop and other stuffs.
The microwave and the refrigerator were very useful to have more privacy during my stay.
There is not a TV in the bedroom, but I don't use to watch TV, so it wasn't a problem for me.
I used the laundry and the dry machines. You must have 2 dollars (in 50cents coins) to use them both, in each load.
There is a shared bathroom, but actually it is not the typical Airbnb where you live and interact with more than 4 persons all the time, so it wasn't a problem for me.
I didn't interacted so much with Vivienne, and I didn't had any problem during my stay.
If someday I come back to visit San Mateo CA, I think that I am going to choose this place again.
