It's a college cafe, so expect students. When we visited, it started rather quiet, but not so quiet I'd feel awkward making a call. Then it quickly filled, likely between classes, at which point it's noisier. Great place for a brief pitstop if you want to get a nice nature-walk in your day, as it's next to the pedestrian bridge over the Reed Canyon, trails and short walk/ride to the Crystal Springs Rhododendron Gardens.
To connect to the college WiFi, connect to "ReedXenia" and register for a password. They will either email or text you a password that works for one week.
