Yes, if budget matters and you don’t mind a 25-minute train commute for old-town evenings. You save USD 40-70 a night on hotels and Esch has enough restaurants to eat out every day. First-time visitors with only two nights should still stay in the capital.
The Belval blast furnaces are preserved and dramatic — visit them. The rest of Esch looks like a normal small European city: pedestrian shopping street, 19th-century train station, some Art Deco. The industrial identity is a heritage layer, not the current reality.
