I had the pleasure of renting a luxury apartment through Realty, and dealt with director Jonathan Alsford in person.
Jonathan was very helpful, and stood by us when the landlord tried to take things slightly beyond what we deemed reasonable.
Realty also provided me with an exceptional lettings reference for my next property rental.
I'm looking to move back to the Dorset area soon, and will definitely give Realty a call. Honestly, the only good experience I've ever had with a letting agent.
