30 days is a short let and you would need a tourist licence to be able to do so. This can take quite a long time at the moment and you have to register to both pay tax on the rent you receive and to register the stay with the police. The bit of good news is that you no longer need to pay tax at the end of each quarter even if you are non resident and they have changed the rules so you do it annually from 2024.
If this is a one off and you know the Spanish locals very well, as in good friends, you could just do it without telling anyone but, again, be aware as they are clamping down on what they call "illegal" lets all over this area.
I also say if you know the family very well as there have been a lot of cases of people going in and then impossible to get them out afterwards. You'd need a very good, watertight contract with them which means you couldn't do it without getting a licence which you have to get permission for from your community and then your town hall.
Quite a lot of advice here on how to get the licence and John123456 has put up some good links on the procedure but people have been saying it takes months and months to get approval.
