I didn't have chance to meet Weixing in person as I just stayed at his place one night, but he sticked the warm reminders on the wall that I had no problem with accessing everything I need when I was there. The room and bathroom are VERY clean. The wifi speed and connection is wonderful, I can work on my remote working station without the significant lag. Highly recommend Weixing's place for the people who are visiting CalTech or attending the conference in Pasadena Convention Center.
