We were a family of four and stayed here for 4 days in May.
Amongst the positives, i) the house is extremely well located in West Pacific Heights. The area is pleasant, safe and easily accessible ii) It is hard to find a centrally located house in SFO that can comfortably house four people, and this house fit the bill (actually, it can take up to 6 people), iii) there was a welcoming bottle of wine and some chocolates which Chris and Neil had very thoughtfully laid out for us.
What we did not like about the place - i) it is very difficult to enter the house physically, the lock requires intricate contortions to reach inside and unlock the main door - it was needlessly difficult, ii) the house is extremely cluttered- there was lots of material just filling up the kitchen, fridge and basement - a little bit of de-cluttering will go a long way in making the stay more comfortable, iii) the house needs more and better located lighting.
