If I understand you correctly you have,
€70k in savings after paying for work on your house,
no mortgage on the house
€20k plus savings a year
a good pension arrangement
In my opinion you should invest, and property could be an option for you. Although the returns are low, see this thread

however you could probably borrow to take advantage of the tax relief on interest, and because of your good income, you would not be in trouble if you ran into any problems withs voids etc.
Are you are happy with the idea of being a landlord ?
In your situation I would borrow most of the money for the investment and for as long a term as possible.
What did you learn from your losses with shares ?
Would you go down that road again ?
By the way and just as an aside,
you are not mid age you are
YOUNG
