As somebody that operates a legal and registered property management company I can tell you that €375 a month is very expensive
Why would you want anybody to visit the property 3 times per week, it is not practical for the management compnay if they are looking after a number of properties plus there is little benefit to the owners, better to have proper scheduled logged visits
You should be looking for a company that is legal, for all sorts or insurance reasons, that have a proper process for scheduled visits, tyically 2 per month but of course you can pay for more whre they check everything, flush toilets, run water, check tghings like boilers and AC plus air the property fully
They should also give you a contract that states ALL of the charges
