I had a long stay of about 3 months at Jennivine's place. The place is very conveniently located. It takes about 5 minutes to walk to the nearest Caltrain station and is perfect for commutes to SF or the South Bay. There are also quite a few restaurants and a gym within 5 minutes walking distance. In addition to the great location, Jennivine is a great host and was very communicative about random things I might need (milk, coffee, tea, fan, ...). The room is very spacious and it is always nice to have a private bathroom attached. I didn't have any issues during my stay and would definitely recommend the place to anyone coming to San Mateo! Finally, the neighborhood is very quiet and safe and I never had problems walking home alone late at night
