We were with this agent for a year and in this time have not been particularly impressed with the service.
When we moved in, the apartment was filthy, particulary the oven which needed industrial strength cleaning twice! when there were problems and repairs were needed, such as when the french doors leaked everytime it rained, they needed constant chasing. The staff were friendly but in no way efficient.
What agent could do to change your mind?
Better care taken of the properties that they are suppose to be looking after and better communication.
