The GRASP lab is in the 4th floor of Levine Hall, the new building of Computer and Information Science at 3330 Walnut Street. From any highway you come choose exit 30th street station. The most convenient parking lots are at the corner of 34th and Chestnut just two blocks from GRASP. See in the map how close GRASP is to the rail-station at 30th and Market. Just walk Market to 33rd, turn left, cross Chestnut, and on Walnut make right. Levine Hall is the NEW glass building on your left, next to the OLD glass building.
