Average and statisfactory salary in Madrid

Hi Redditors!

Surely enough this has been spoken, but I wanted a recent update on the topic.

Which is realistically the average brutto yearly salary in Madrid?

How much should, instead, a couple with two kids (that needs to rent an apartment) bring home every month (netto) to have a decent and satisfactory life?

Please, let's give just realistic, based on facts, and not polemic answers.

We are moving to the city for family reasons after many years in another, richer, European capital and wanted to have an overview on what to expect and so on.

Thank you all!
