I love Strasbourg. It feels like a small city with big heart. Old half-timber houses sit by calm canals. The cathedral towers above everything. The vibe is cosy and a little quirky. People speak French and German. Food is warm and hearty. Winters get cold. Summers are warm and pleasant.
For digital nomads this city works well. Internet is solid. There are good coworking spaces and cafes with Wi Fi. Most travellers enjoy biking here. I once watched students picnic by the canal and start an impromptu guitar session. Cost of living is medium. Cheaper than Paris but not a bargain town. Community is friendly. You will find expats, students and remote workers at bars and meetups. Things to do are close by. Day trips to the Rhine and German towns are easy. Arguably not the best for sun seekers. But for history, food and a calm work rhythm this place is amazing for some people.
