The bad: Well, things started off on the wrong foot. My flight was a little delayed, and I got into SFO a little after 8PM. I contacted Peggy about this, but she would not let me check in late, even though I had already paid for my night there. I politely asked her if she could be flexible for that night only, and just leave me the code or something, but just repeated what she had already sent me, which was "check in ends at 9PM." There was no flexibility here, though she told me I could check in a little early the next day, which was not helpful for me at all. I was pretty upset about this after I did check in, because there isn't even a lock on the door, so I could have easily stayed there that night, with no extra effort on her part. I also texted her one morning because I had trouble figuring out how to turn the hot water in the shower on, to which Peggy never followed up or responded to this message.
The good: I like the area. It feels like a safe part of town, but still interesting. There are shops and a grocery store within easy walking distance. It's not super close to BART, but if you like longish walks (about 1.5 miles), or don't mind taking the bus, it's not a huge deal. The downstairs space is clean, even though there are a lot of people staying in a small space. I did not use the kitchen upstairs during my stay.
