We went through an agency, we paid one month's rent, one month's rent as a deposit and the agency fee was also one month's rent. When broken down that's the equivalent to 3months. Private landlords we've had (two) havent paid back the deposit, but tbf to our last landlord we didn't pay the last month rent which was fair.
If it's the woman in question that's bothering you and the change in prices then walk away from it, she maybe an official agent and also his friend, who know? You DO NOT need to pay a cleaner, that is a luxury that rich people have. If they keep adding things on top that are extra then walk away, don't let them take advantage. Some place charge for bin services and that's absolutely normal and the whole community pays for it and it's well worth it, that's the only extra we have ever had to pay
