Most of them are built on good-sized lots. Don't know how they snuck in there. Los Altos has a lovely downtown shaded with tall redwoods, pines and other trees. Many world-class restaurants call Los Altos home. There are sidewalk cafes, boutiques, art galleries, coffee shops, bakeries.
City also has seven shopping centers.
The schools are excellent, at the top in the state rankings. Day care is available at the elementary schools. The residents consistently pass taxes and bonds to pay for the schools. Foothill Expressway runs through town so the commute is not bad. Also the 280 and the 101 are close by.
