The room was exactly what I needed for my stay: a comfy bed, a bathroom and a kitchen. All three have multiple amenities. Especially the bathroom has, looks like, all utensils: from toothpaste to multiple skin/hair-care stuff. It's placed near the ocean, there're two metro lines in 20 mins (L and N) and multiple buses, most notable is #7 going Downtown. So it's not a problem to get almost anywhere by public transport. There some places to have a snack and groceries at Noriega St. a couple of blocks north.
Joey was a lovely host, that's a pity we didn't meet in person. She answered really fast, was friendly and hospitable, helped with all my demands. I'll definitely stay there again.
