Stayed for a month!
Room - As mentioned by other reviews, 1 thing is that the window is unable to be opened. However, the hosts and owner was nice enough to lend me a fan during my stay which made it very comfortable. The bed is also nice and there is a drawer, desk and mirror for you to use.
Other areas - Living room is super nicely furnished. Alot of cooking ware is available for use so its super nice and easy to cook! Washing soap / hand soap are also available so its super nice. Bathroom is also thoughtfully equipped - there are cotton buds etc and the shower is clean :). Dryer is free - washing machine is $1.75 which is really affordable as well! Wifi is also included and super fast :)
Location - The area is 1 block away from San Bruno - a super cute street. Its filled with Asian food (Chinese & Vietnamese), hair salons, boba tea and some american diners. There's alot of supermarkets (Mexican and Chinese) down the street as well. Safety wise is extremely safe - no issues with anything whatsoever. It may be far especially if you want to head to inner Richmond but bus 8 is extremely convenient to bring you to the city (since it goes via highway). Bus 9 gets a little sketchy at night from the city but otherwise I took bus 8 from the city most of the days so was extremely happy with the location!
Hosts - The owner and hosts were super nice! They offered me use of a fan as well as accommodated to my schedule as much as they could. They were also super responsive which made the stay super pleasant
Overall 5/5 for the location and place :) Portola is a super cute neighbourhood and its really safe as well! While the room would a little stuffy sometimes, everything else made it worth the stay!
