    "This area cannot be beat...we walk to all of the fun downtown festivities, local shops, restaurants, pubs, bistros, and some onf the finest cuisine in America within a 5-block radus. We either walk, bike, or bus to everything, we love that we almost never have to drive! With the mountains, Farmer's Market, Boulder Creek, and theFamous and FUN Pearl St. Mall on one side, and a beautiful little pocket park, Whole Foods, Trader Joe's, and the trendy 29th St. Mall on the other...the Whittier neighborhood around 23rd and Pearl is the PERFECT little slice of downtown living! We wouldn't live anywhere else!! "
