This cute flat is comfortable, spacious, and ideal if you'd like to live like a local. It is located on a smaller residential street, so it is very quiet. There is a good-sized living room with a couch that can be used as a very comfortable bed, There is also a good-sized bedroom with a very comfortable bed. The bathroom is through the bedroom, so if multiple people are staying, it is best for them to know each other well. The kitchen is large with a table for four, and it was well-equiped, including filtered water and tasty goodies left by Donna.
Communication with Donna was easy, as was the check in/out process. Everything was just as expected, so there were no unwelcome surprises.
While neither of these caused issues for me, it is worth noting that at night the street lights do shine inside, and while the living room has room-darkening shades, it is a bit bright inside. If you are bothered by the light, this would be a good time to bring your sleep mask. Also, the shower is in a classic claw-footed tub that has high sides. If you'd have a tough time climbing in and out of the tub, this might not be your best choice. It can be a bit challenging, particularly if you are short.
In all, I had a fantastic stay, and will keep Donna's place in mind for the next time I'm in San Francisco.
