Vanguard is a wonderful host and while it may be a little confusing to enter the building, it is 100% worth it and they provide all the details required to enter. Great location with a ton of things within walking distance and even better if you’re willing to walk further than a mile or two. Do not hesitate to ask any questions, they will be answered in a timely manner. Would definitely consider staying at his AirBnB the next time I’m in Seattle.
