Helen's place was great. I was visiting to speak at a conference at Stanford and decided to book an Airbnb instead of a $300/night hotel near campus. Check-in instructions were accurate and it was easy to get a Lyft to campus. It's about a quick 20 min ride (20-35 min if you do LyftLine) that ran $7-$15 depending on the time of day. I can't speak to the neighborhood since I basically only showered and slept here, but it seemed quiet and safe. The room was bright and airy, I never felt cramped and had plenty of room to spread out and a desk where I could work. I will definitely stay here again if I'm in the area!
