I stayed here for a month while I was between apartments and while it's small and not my typical taste in decor, by the end of my visit, I loved it and was sad to leave. It has such a unique vibe and even though it's small, it's nice that it has a separate bedroom and even stairs up to the kitchen and bathroom so it feels larger than it is and I miss having separate spaces like that now that I'm in a big open plan studio apartment. Also the couch was super comfy and it even has a real desk and desk chair that I used for working from home (good Wifi speed too!). The host was very responsive to any issues I had and was kind enough to let me park in the driveway and use the laundry twice during my stay, both of which are conveniences that are hard to find in SF, so I found that a huge benefit to this place! Also, the proximity to the West Portal MUNI station and all the great shops and restaurants can't be beat (5 min walk). There's a Safeway about a 7 min drive away but it's walking distance to the West Portal Produce Market which has a wide selection of fruits and vegetables as well as canned goods and even eggs and some yogurts and milk. There are also many lovely neighborhoods to stroll through nearby and you can even walk up to Mount Davidson! (but I recommend doing that on one of the few non-foggy days so that you can see the gorgeous view. West Portal is a much foggier neighborhood, by the way, than the East half of SF)
I would say the only slight negatives are that, as others have mentioned the bed is very small and also a bit old and saggy, so while it was fine for me by myself, not sure it would be comfortable for two people. Also, there is very limited counter or cabinet space in the kitchen so it was difficult to cook anything other than meals with only a few ingredients. The thing that I think could be the biggest issue for some is that the gate and pathway down on the side of the main house to get to the rental unit is extremely narrow and with intermittent and uneven steps. I'm a skinny 5' 3" woman and it was no wider than my shoulders. While I managed, it did make loading luggage in and out or even carrying bags of groceries a bit tricky since you had to carry stuff in front or back of you or walk sideways but then it was hard to see where the stairs were. In any case, for people with mobility issues or even with large luggage, you might want to try some place else. For everyone else, it's not ideal but definitely manageable.
