Fléville-devant-Nancy is about 10 km south of Nancy city centre. The most practical way to get there is by car — the drive from central Nancy takes around 15 minutes via the D974. There is no direct train service; the nearest station is Nancy, which has fast TGV connections to Paris (about 90 minutes), Strasbourg, and Metz.
If you are arriving without a car, taxis from Nancy are your best option. Local buses connect some villages in the Meurthe-et-Moselle, but connections to Fléville are infrequent and poorly suited to a day visit.
