I received a letter saying the letting agent is coming to check the property as we've been in it three months, and then from there on, they will come to check once every four months (pain in the arse. Baby on the way. We've decorated beautifully but without asking, feels like an invasion of space etc). However, I can cope with this until she said 'you don't have to be there, we can just use our key, let ourselves in and have a look around'....
Surely they're not meant to have a key? Let alone let themselves in for a poke about? Say money went missing or something? I think it's a little shady.
