This was a good, inexpensive place to stay for my purposes. The space is a bit more like a hotel room equipped with a kitchenette than what I would call a "studio." There's a bedroom with a bed, desk, chair, TV, and side table, and the kitchenette with a mini-fridge and microwave. It had everything I needed, but wasn't exactly an apartment. But everything was clean and orderly, and Alex made check-in really easy (I arrived late and needed lockbox instructions, which he provided promptly) and communicated well throughout. The bed was also comfortable.
I'll admit, that stretch of 7th Street doesn't look great - I had moments when I wasn't sure if it was entirely safe - but nothing at all happened. It's easy walking distance from other spots in downtown, and very close to the ferry that takes you to SF.
