I stayed at Tracy's for 3 nights to attend a conference nearby, so I didn't spend much time hanging out at her place, but the Airbnb was everything needed it to be- close to the conference, comfortable bed, nice private space. Tracy is very warm and welcoming, and the room had a welcome basket with water, brochures and a welcome note ready to go. She has multiple guests over staying at a time, some of whom are more long term guests- I was the only short term person staying at the time. I didn't have too much interaction with the other guests and we were never on top of each other in line for the bathroom or anything like that.
One thing to consider is if you are checking in on a weekday morning, this might not be the best place for you. Tracy has morning errands (I think dropping off the kids?) and then has to get to work not long after, so the window of time that she's home in morning for check in is pretty tight. I had taken a red eye and was hanging out at the office nearby until Tracy was back, so it was fine for me, but I can imagine this tight window being problematic if you have a flight delay, traffic into the city, or just simply can't make the weekday morning check in window.
