Stayed at Vanick & Deborah's place during a business trip to SF, and very much enjoyed it. The space is indeed charming, and very comfortable. It's located at the basement level of their residence and therefore doesn't have much natural light, but it's quiet and feels safe. Vanick & Deborah managed to be welcoming and hospitable (even inviting me up for a beer with their friends!) but at the same time respected my privacy. And when the power went out on the block my first night there, Vanick brought down a collection of candles for me, which ended up adding to the coziness of the space. The "area guide" they provided was very helpful - I only wish I'd had more time to explore the area! I would definitely stay here again.
