I love flying in Spain.My opinion,there are less complications and it is not too expensive,except San Sebastian (but so scenic).
I landed in Fuentemilanos,Valladollid,San Sebastian.My hope for 2021,depending covid,will be burgos and cuatro vientos (Madrid).
Never problems with air control,english language not too bad,and even at large airports,no stress,large areas,so you don’t change often radio frequency.
