Number one tip: Communicate! If something happens there is no need to be afraid, but it is worth notifying the landlord as a matter of urgency. Communication could be in a form that leaves a written mark (e-mail, messages, etc.), which can be proven later if necessary. Then it's worth waiting to see what the landlord suggests.
If the landlord's solution is not satisfactory or no suggestion is received, the tenant can ask for an impartial opinion from the Rendin experts. That is the great value of concluding the rental agreement via Rendin. However, in our experience, most landlords are very sensible people and most concerns are resolved through compromise.
