Quite near Needham line, but still in Newton Center.
From Newton Centre, take Centre Street southwest (away from Newton Corner) past Newton Highlands and under Route 9 where it turns into Winchester Street. At the intersection with Needham Street, there's a light; continue straight on Winchester Street. Where it ends, turn right on Nahanton. At the first light, turn left onto Wells Avenue. Take your first left to remain on Wells and then the third driveway on your right is #200, home of the Russian School of Math and Dance Fever Studios. Mapquest and GPS are only approximate; when you near the location, follow the street numbers to the right place on the circle. The building has two parking lots; use the larger one, and you will find plenty of free parking. Go in the front door, take a right and enter Dance Fever through a glass door. Go straight ahead toward the little break room; turn right and go to the far diagonal classroom, which is ours. No food, no drink, and no shoes in the room due to the sparkling hardwood floors!
OR From Route 128, take Exit 19 onto Highland Ave heading into Newton. Keep right at the fork to continue toward Kendrick Street. Turn left onto Kendrick Street which becomes Nahanton Street. At the light, turn right onto Wells Avenue and continue as above.
