Overall great unit and great location. A few things I would have liked to have known:
The futon was not comfortable at all. It is hard and leather and the seam when folded down was very awkward. Thankfully my sister lives around the corner and was able to bring me a thick memory foam mattress to go on top. There is no way I could have slept on the futon and my two other family members agreed. My recommendation is to put a daybed in there with a real mattress for guests.
Also, the room with the futon does not have a door, so if you were expecting to have privacy in that room there isn't any. Luckily I was staying with my mom but it could have been an awkward arrangement otherwise.
Also there is no thermostat in the unit, it is controlled by the main unit which I guess is common in SF but it felt like a bit of an inconvenience. Adding a fan to both rooms would be nice for guests. I also borrowed a fan from my sister because the room got stuffy. Would rebook with changes made.
