Steve and Sara are excellent hosts; happy to give you space if you need it but ready with information, advice and conversation if you look for it.
Highland Park is a great location. I enjoyed the feel of the area and it's well placed for exploring greater Los Angeles.
S&S are putting a lot of work into the house and its outbuilding and I applaud their decision to go solar.
Couple of recommendations; Bon Vivant Market & Cafe over in Atwater Village is worth dropping by (drive the back way - much more fun) and Golden Road Brewing by the railway near to the 134 does a very good selection of beers and has a great atmosphere.
