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. (Nahanton Street may also be reached from Kendrick Street in Needham.) At the first light, instead of turning right into the JCC, 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 Math School and Dance Fever Studios. Mapquest and GPS are approximately correct; when you near the location, follow the street numbers to the right place on the circle. The building has two parking lots; use the one that is available, and you will find plenty of free parking. Please obey the sign on the lot that says, "Do not park here." Go in the front door and take a right and follow the hallway around. Our room is the first studio on the left. No food or drink or shoes in the room due to the sparkling hardwood floors!
OR From Route 128, take Exit 19A onto Highland Ave heading into Newton. Take your first right on First Avenue and follow as it forces you to turn left onto B Street and right onto Third Avenue. At the end of Third Avenue turn left onto Kendrick/Nahanton. At the light, turn right onto Wells Avenue and continue as above.
