Cozy apartment in a charming building, close to the beach and downtown

Everything was fine until we saw the bathroom. The shower is completely full of mould. We contacted the owner , who send the cleaning lady. We waited for her to come and tell us that she will come later ( first day ruined) she came later , cleaned a little , couldn’t remove the mould and informed us that she will come the next day. So again we waited for her the next day ( second day ruined) to inform us that everything will be done another day completely new by a plumber. Nobody showed up in the morning , nobody showed up in the afternoon ( although the owner told us to wait in the afternoon) Finally the next day the guy showed up to make new silicone ( but only inside the shower at the bottom, he cannot repair or clean all mould) and to inform us that there will be no shower possible for minimum 24 h. This of course was impossible. I contacted the owner : no answer anymore. I am not complaining about dirty walls, pans, dishwasher ( which actually is unusable because everything comes out as dirty as you put in) The washing machine is molded also , but this i don’t need. There is not enough cutlery for us..... All this is not a big issue. But all together spoils seriously our vacation
