I did not get a chance to meet Dennis in person, but he is very responsive through email/phone text. I needed to extend my stay for another night and he was being flexible. The house is located in a quite and safe area; the house is close to downtown San Mateo. The interior of the house is very neat and clean; it has a very nice backyard with swing set. I stayed in the Palm room with lots of storage space. It was a pleasant stay for me, overall. I will definitely consider this place again next time I need a place to stay in San Mateo area.
