Joe is patient (we arrived late) and very kind as he bought us cakes, he also left a lot of food so we didn't have to look for food while arriving.He took time to explain everything about his loft (where are the lights, what we can use,...), great places to eat,to visit.
The place is as described on the website and we were surprised: it is bigger thant it seems on the photos, we felt at home.He gave us a parking pass so it was free to park near the loft.One thing you have to know is that the street is 45 degrees steep so it takes a little time to park,
and it is not easy to get out of the car lol, but there are some parking places that are flat very near (come early if you want to park there).
I would recommand this place to visit SF.
