This is a really neat house with cool people in it. There are 8 guests at any given time it looks like, almost all between ages 23-30 from several different countries and all here for work/internships either at JPL or Cal Tech. So, bright people interested in a wide range of things - there were several nights where we just gathered in the kitchen to hang out and it was a really fun relaxed atmosphere. But then it became silent around 10pm, and stayed silent until the morning. Ideally located in a pretty safe neighborhood in Pasadena, there're busses to Cal Tech/Pasadena Convention center every ~8 minutes, and it's only a 10 minute walk to the nearest metro station which provides a direct shot to Union Station.
