I spent 28 days at Dan's place. Overall very nice private place! The place looks exactly like what the pictures depict. The price/value seemed the best of my search for an affordable private place and it did not disappoint.
Dan responded to my booking request extremely quickly. It was very convenient to book the place.
Check-in. Dan met me in the front and let me know about all the important things, like how to open/lock the door, how to deal with parking, and the various amenities within the home. Dan was very responsive to any additional questions I had. On move-in the place was relatively clean, though I cleaned the floor a bit more because I like to take off my shoes inside.
The bed is firm (which suits my preference), and extra bedding was supplied. The bathroom has a nice tall shower, I could comfortably stand at 6'. The mini-kitchen is well equipped with a gas stove, pots, pans, utensils, dishes, though any serious cooking will be hampered by ventilation and the small sink. There is a fan and space heater offered if it gets too cold or hot. Wifi was good, though could be a little spotty in certain locations of the place.
Privacy was great, the entrance is in the back and there is a high fence so the place feels safe and secluded. Noise level was good, the only minor detractor being a dog a few houses away that likes to bark.
Location is convenient and very close to the highway. The parking in the immediate area can be difficult to find, but if you have a small car Dan can help you sort out a very convenient parking fallback. It about 15min walking distance from central downtown San-Mateo.
Accessibility notes: the path to get to the entrance is pretty narrow, about 3ft across assuming you don't want to rub up against the house/bushes. This path can also be pretty dark at night. There are 3 steps up as seen in the pictures.
