Good place to stay if you're staying in Palo Alto. It's on the southwest side of the train tracks, which is a huge benefit if you want to bike to places on El Camino. Ample room, great communication from the host.
Note, the kitchen is very small, so you can't use multiple appliances at once.
Also note that the studio is connected to the host's house, it's not standalone. The entrance is very accessible though, and totally private. It has it's own little front garden area too. Super nice.
