Mary is a fantastic host, very responsive and helpful. Her place is clean and well laid out. I enjoyed having other guests around, it was pleasant to have people to talk to instead of stressing about taking Step 2 CS. Regarding getting yourself to the testing site, if you didn't drive I recommend taking an uber or lyft because the way the sidewalks are laid out it's a 23 minute walk (per google maps) to get there. But if you grab a lyft it will be like 5 min. Mary's place was a very enjoyable place to stay, if (God forbid) I failed CS, I would try to book her AirBNB again next time I take it haha.
