Good value for money and experienced host. The position is good if you have a car since it's close both to the center and the freeway. Not as good if you like walking around, but who walks in California? Anyway it's just a 25 minutes walk to Caltech, bus and metro stops are relatively close and there are always Uber/Lyft around. The place was clean and well equipped. The only problem that I had in an otherwise flawless experience was with the WiFi connection: the signal was weak and too unstable to make conference calls (which I needed to do at times when cafes or libraries were closed).
