Prices soaring lately due to inflation. They are almost twice than what it used to be a couple of years ago.
Eating outside in a restaurant you spend easily 15-20 euros. Then a coffee/tea at 4euros, beer/wine 5-7euros.
Let's say accommodation, museums coupled with a measured lifestyle you would need 150euros a day. But at the end, you can reduce/increase that amount. It all matters how much you consume, the comforts you select to have around you etc.
