Due to its German heritage, and military tradition, Metz is quite not liked town in France but most of the criticism about Metz is cliché. In fact, Metz is a unique town in France thanks to a great historical background and features a beautiful old town built using the "pierre de Jaumont", a local yellow colored limestone.
Even though Metz is close to Luxembourg and Germany, locals are not fluent in German and speak French just as any other French cities. The local dialect (Platt) is spoken in some parts of northern and eastern Moselle but has never been spoken in Metz.
There is a small regional airport for Metz and Nancy (code: ETZ), located southeast of Metz. This mainly handles commercial traffic, but there are passenger flights to/from Paris, Lyon, Algiers, and several Italian destinations.
A shuttle bus  is also available from Frankfurt-Hahn airport.
Metz is also reachable by train (including TGV), with connections to/from Paris, Luxembourg, and Strasbourg. The train station is at the southern edge of the city center. You should note that if you have a eurail pass you will probably not be able to leave for a few weeks (you must make reservations way in advance).
Driving in the center of town is not recommended. Park in one of the parking areas (well-marked from the main roads in) and walk or use public transport.
Be aware of immigrant beggars in parking areas offering to watch your car and approaching you at ticket machines when your wallet is in your hand. Local police refuse to prevent this activity even though they accept it is illegal and keeps visitors away.
Everything in city center is easily accessible on foot, and much of the main downtown/shopping area is pedestrianised. Be warned, though, that there are a few hills!
Bikes are also a great way to get around, though the same comment about hills applies here too.
Cathedrale St-Etienne, place d'Armes. The Cathedral is a truly impressive structure, overlooking the river and the city. Inside, both its height (the third-tallest nave in France) and its stained glass windows (reportedly the largest surface area in France, with several by Chagall) will impress visitors.
Place d'Armes, the square next to the cathedral, is notable for the four buildings that surround it. They were specifically designed to show the balance between the various local powers: religion (the cathedral), the military (now converted to the tourist office), civil government (the town hall) and justice (the court building). Place d'Armes also hosts a regular market for produce and other local goods. The tourist office is along one side of Place d'Armes.
The Covered Market, opposite the cathedral, was historically the bishops' palace. Today it hosts stalls selling meats, cheeses, and other regional specialities.
The Opera-Théâtre, not far from the Cathedral, is a theatre and opera house, built between 1732 and 1752 and the oldest in France.
The Railway Station (built in 1908) and its imperial area built during German occupation.
If the weather is nice, rent a bike and head south along the river in the direction of Nancy. Paths are well-marked, well-maintained, and mostly flat. Bikes are available next to the train station or across the street from the cathedral. Cost is €10 per day (but requires a credit card number or cash deposit of €100 per bike).
In December, Christmas markets can be found in many places. They are the best places to drink hot wine (vin chaud).
If you want to see sport games, professional teams includes: FC Metz (football), H2ML (women's handball), SMEC (men's handball and table tennis), RC Metz (rugby). If you want to see ice hockey games, you can drive to Amneville which is home of the "Amneville Galaxians".

Metz is quite a safe town. Avoiding suburbs like Borny or St Eloy, and the old town small alleys, by night, is however recommended.
In the centre, some people are likely to ask you to give them €1 or 2, a cigarette or even a mobile phone call. These people are not beggars or poor, they're just lazy and feel like they can get what they want just by asking people. Don't be intimidated and feel free to say no. Some of them might tell you a dramatic story or offer you cards for "charity." Don't support this and tell them no.
