The Bartlett is okay. The location (Union Square) is ok, but not great. Personally, I don't like this area and I don't feel safe in this area.
The Bartlett staff is nice and communicative but check in was kind of slow. In addition, there's no cover on the comforter/no duvet cover; when I asked for one, I got a new comforter (also without a cover) dropped off at my door sitting on the floor in the hallway.
I wasn't given a check out time when I arrived/checked in, so I was taking my time checking out and housekeeping walked in on me changing/using the restroom. I just overall wasn't impressed with the quality but the price for SF overall was fair.
I won't stay again personally. The area just is grungy and unsafe feeling to me.
