This was by far the nicest airB&B stay I've had, and my work has me travel a fair bit. The physical space was excellent: clean, attractive, secure and functional, with many nice details attended to. The location is awesome, a quiet and safe neighborhood that you would never think was in the heart of SF, yet it is. Gracious and helpful hosts, effortless check in and out, just a great example of the best of air b&b.
