The check in process was incredibly convenient and flexible! The street parking isn't exactly "ample" and there are many restrictions for multiple days of the week, so definitely keep that in mind. We had to park a few blocks away the first night we arrived.
The room itself was nice and simple, exactly as advertised except for the fact there was no tea or coffee in the room itself. However, there were plenty of water bottles available for our stay. The host offered to provide us with a few tea bags that we could put into microwaved water and mentioned we could buy coffee across the street. The two nearby cafes apparently offered the worst coffee imaginable and my SO took one sip before saying "1/10," so there's that!
The garden really is beautiful and the wi-fi is fast. I wouldn't classify a 20-25 minute walk to public transportation as "close", but it is possible to do that!
All in all, a good stay with a good host, but I left here thinking San Francisco is a doozy.
