I have 4 and I feel like it's just the right amount for us. I use them two or three times before I wash though (I hang them to dry in between bathings...)
We only received 2, and that was not enough! I'd say 6 is about right. Now that I've gone back to work, we aren't able to get as much laundry done. (I'm a use a towel once and then wash it person)
