We had a long wonderful stay at Paul's home, which is much more gorgeous in person than in the pictures.
The space is divided into two section, one is the kitchen, dining, and living areas, and the other is the back of the house which holds the bedrooms and bathrooms, and the two are divided by a door. This was very convenient for us so our one year old can play while we worked during the day, and we could watch a movie, while he slept quietly at night.
It's the best of two worlds. It's the owner's home, so it has all the amenities and personal touches that you'd want or need for a long term stay, and at the same time, they've removed all their personal items, so you have closet space, and pantry space, and it doesn't feel like you're imposing on someone else's home.
Internet is fast and reliable, and the owner was courteous, and quick to follow up with any issues. It's well connected to bus lines, and close to parks and restaurants. I'd highly recommend Paul's home to anyone considering a short or long term stay in SF.
