I have used spencers quite a few times in the past, to rent out my properties. The agent Tracey in Lettings is a 'marvel', polite, exceptional with tenants and landlords/landladys, never having to go back on her word. She is a credit to her company. I have recommended her to several of my friends and work collegues, who I know have used her to rent out their properties, with ease.
I would suggest that every company has a Tracey on board, it would definately change the estate agent image.
