After my long search with many agents, I decided to go with to Morgan Randall. They seemed to have a different approach to other agents. They actually listened to what I wanted and matched my needs to the apartments available (in particular, I wanted outdoor space and the agent didn't show me any flats which weren't suitable).
I've been on so many pointless viewings with other agencies. Ashley at Morgan Randall really did set the bar high, It was a delight being assisted by him. He was also responsive when I left messages to call me back.
