Could anyone tell me if it's normal that the temperature gauge (on the control pannel) indicates temperature higher than 90ºC or it should stabilize at that value?

Normally the temp gauge should be around 90 degrees, sometimes slightly less, but it sounds like you have a blown head gasket. To double check this see if you have a creamy/oily water in your coolant tank, if so then your gasket has gone.
