I love Takoma Park. We've been here for over 10 years, and I have zero interest in moving.
I don't have any kids in school so I don't know much about that, though most people I talk to seem happy with the schools. Note that not all elementary students in Takoma Park go to Takoma Park Elementary -- where I live, kids go to Rolling Terrace (with its Spanish immersion program) instead.
Takoma Park has much more of a community feel than most places in the DC area. We have our own local police force, our own local library, our own parks, festivals, city government, etc.
It's pretty crunchy, with a farmer's market, cooperative grocery store, attachment parenting group, la leche league, birthing circle, active homeschooling community, etc.
I'd say that Takoma Park is perfect for crunchy people who are comfortable living close to the urban center. It won't be right for you if you want more of an "outer suburbs" feel, and certainly not if your dream is to live out in the country.
