We were in Topanga Canyon in early March for my cousin's wedding, and it was cold there! Bring layers!! It took a little trial and error with the heater in the main house so it was cold occasionally, but we mostly got it figured out. The hot water takes a minute or so to kick in, and then there was plenty for all of us to shower. We enjoyed our stay at Jennifer's place, the location worked out really well for us, and Jennifer communicated well about the few questions we had. Thank you!
