House is beautiful, tastefully decorated and immaculately clean - I especially appreciated that the kitchen was stocked with light food and drinks (fruit, yogurt, cereal, coffee, tea, milk, etc.). Maria was charming and fun to talk to, and her dogs are sweet and well-behaved.
A couple of issues about the room: What there is of it is comfortable - good bed, a selection of pillows, a closet with a small dresser in it , a nice desk for working. However, that’s almost exactly all there is - that room is tiny. Suitable for a solo traveler, but two might feel a bit cramped. Also, there’s no exterior window (the window that shows in the photo opens into an interior stairwell), although there’s a stand fan that does a good job keeping the air moving. Also, if stairs are a problem for you, this is not a good choice - there are a few stairs up to the front of the house, and a long flight of stairs up to the flat. House is shoe-free and there’s a strict “no food in the bedrooms” rule, although the living/dining room is a pleasant place to sit and eat,
The location couldn’t be better, at least for my purposes (I was in town for the Folsom Street Fair, a block away). You can walk to dozens of restaurants around SoMa, to bars and clubs, to coffee houses, to an excellent hardware store and to a gourmet grocery store. BART is nearby too, although I didn’t use it on this visit. However, if you’re used to the quiet of the country or the suburbs, SoMa may be a bit chaotic for your taste.
All-in-all, I really enjoyed my stay at Maria’s, and would recommend it to any other city-loving solo traveler who doesn’t mind stairs.
