We love love LOOOOVE this place. We rented it a few years ago for my dad's 80th birthday party (with approval from Bill and Carrie of course). It was the perfect place to stay and also to host family for an afternoon. This time we were in Whittier for an official family reunion and rented with some cousins. We had 5 adults, 2 kids, and our 9 month old baby. We were all very comfortable and never felt cramped at all.
The master bedroom is fairly large with a nice big walk in closet where we set up our baby's pack n play (they actually had one in there already that we could have used too). The other 3 bedrooms are modestly sized but definitely big enough to unpack all your luggage, get comfortable, and sleep peacefully. The common area is really large, boasting a huge, open, eat in kitchen with seating area, and a nice sized dining and living room area. More than enough space for everyone to spread out and have fun.
Parking was always easy, right in front of the house, even on the day that there was a street fair nearby. You can easily walk to all kinda of shops and restaurants on the absolutely adorably quaint Greenleaf of Uptown Whittier.
Obviously I have nothing but good things to say. If you're looking for a place, and this one is available, snap it up right now because you will find nothing better!
