My partner and I stayed at Robert's guest house for 4 nights May 2015 and it was great! Robert was very quick to respond any time I had a question, and he was very accommodating with helping us get checked in and out at the right times. The house is fantastic, great view of the hills, the Griffith Observatory, and (when you can see through the smog) downtown LA. As he says, you are right next to the Hollywood sign with a short hike (we opted to just get some great pictures from the street), and with a ~5 minute drive you're in downtown Hollywood, so the location couldn't get any better. The only complaints I have are really with LA, not Robert, so I won't enumerate them here, but all in all, Robert's guest house is a great little spot to spend some time while you're in the area, and I'd stay again in a heartbeat. Thanks Robert!
