€5200 net/month in Luxembourg

Hello,
We (me and my spouse) are planning to move to Luxembourg with my net income €5200/pm. (my spouse will be dependant on me until she gets her medical licence to practice in Luxembourg)

Is it enough to live a decent life?

(How does it compare to living in France? We currently live in south of France with €3500 net/pm, which is kind of OK for us. We save about €300-400/month)
Thank you
