Vivian's place was near our place in Diamond Bar, beautiful surroundings, great hikes and local mom and pop dining and close to freeways. It's extremely quiet too for a good night's sleep as opposed to even 5 star hotels in Anaheim...
Vivian was a great host too, accommodated my needs and had everything in the room for my stay. Clean sheets and towels too, which are important to me.
I can highly recommend for travelers.
