Why should I pay the landlord to find a new tenant?

Questioner

I rented a room, but due to personal circumstances I could no longer stay in the room and I immediately informed the landlord (beginning of April). He still asked that I have to pay the month of May in between that we find another tenant together to take over my contract. Finally I had to pay the month of May knowing that we already have a tenant and that he could move in right away. On May 8th I took everything out of the room and gave the new tenant the keys. Today I received an email stating that 240 euros will be deducted from my deposit for finding and processing a new tenant. It also says that I paid 137 euros for the month of May which means until the new tenant signed the contract and took me over. My question is why should I pay 240 euros if I kept paying the rent until the last minute?

Lawyer

If you cancel the rent at the beginning of April, you still have to pay the month of May because there is a one-month notice period. Of course, you do not have to reimburse the costs for finding a new tenant.
